Work the following probability sock problem, keeping in mind that this is a problem without replacement. When you take out a sock, it stays out.

Sock Problem:

Your sock drawer is very unorganized. No socks are paired, and they are all just thrown randomly into the drawer. You do know that the drawer has four red socks and four blue socks in it. You want to get some socks to wear in the morning, but you do not want to turn on a light for fear of waking up your family.

• If you draw two, what is the probability of a red pair match?
• If you draw two, what is the probability of a match of any color?
• If you draw three, what is the probability of a match of any color?
• Describe your thinking and process.
• Include your thinking/reasoning on this problem, answers to the questions in fractional form (not decimals or percentages), and the specific thinking path that led you to the answers.

Que. Music can be viewed as another agent of socialization. For this question, you are to analyze the lyrics of two songs (they can be of the same genre of music or from two different genres) to demonstrate socialization through music. Use your sociological imagination and discover what socialization is occurring in these songs. You are to identify the cultural lessons (the norms) that are constructed in each song. Tell me what you discovered about the lyrics and what does this convey about socialization? Explain.

[NOTE:  You may focus on how the song lyrics convey ideas related to behavior, gender, interaction, money, current events (for example the “protest songs” of the 1960’s), or any other “norms” that are conveyed through the lyrics.

In a study, 80 men are tested and 7 of them have red/green color blindness. Construct the 99% confidence interval for the percentage of all men with red/green color blindness.Also find the margin of error. Round your answers to 3 decimal places.

A newly built casino is introducing a new gamble. Since this game is extremely new, the casino is offering a free play to everyone (no money or chips needed to gamble) so that all players get a sense of this new game. The game is played with the following rules

There are 3 decks of 20 cards each on the table:
• Deck A contains 20 red cards numbered 1–20.
• Deck B contains 10 red cards numbered 21–30 and 10 blue cards.
• Deck C contains 5 red cards numbered 31–35 and 15 blue cards.
Each of the 3 decks is shuffled, and 1 card is drawn from each deck. These 3 cards are shuffled and put
face down on the table, making a new pile of 3 cards. Let R be the number of red cards among these 3
cards.
a. Compute the expected value and the variance of R.

Parts b–d describe three different ways in which you could learn that the pile of 3 cards formed above
(with 1 card from each of the 3 decks) has 2 red cards. In each case, determine the probability that
the third card in the pile is also red. Note that these three parts are all independent—for example, the
information given in part b does not carry over to parts c or d.

b. The 3 cards in the new pile are turned over one at a time. The first card is the red 32, and the
second card is the red 5. What is the probability that the third card in the pile is also red?
c. The 3 cards in the new pile are turned over one at a time, but you only see the color on each card
(not the number). The first two cards flipped over are red. What is the probability that the third
card in the pile is also red?
d. You ask a friend to look at the 3 cards in the pile without showing you the cards. You ask them,
“Are there at least 2 red cards in the pile?” They confirm that yes, there are at least 2 reds in the
pile. What is the probability that all 3 cards are red?

1- Why is the FRAP technique applicable only to live cells?

2- A researcher wishes to confirm that the adenine nucleotide translocase (ANT) is localized to mitochondria by using immunofluorescence microscopy. He has an anti-ANT antibody fluorescently labelled with Alexa Fluor red and plans to show co-localisation with mitochondria using mitotracker red. Why will this not work? Suggest a better approach.

3- Briefly describe the principle of the FISH technique and indicate one type of sample that this technique could be used with.

4- You are working in a lab that had access to a range of deletion collections. A company approaches your supervisor with a new drug that has great anti-tumor properties and also inhibits the growth of yeast. The company wants to check that the mechanism of action of the drug is novel. That is, it is not similar to other known anti-tumour compounds. what techniques could you use to:

a. Demonstrate the drug has a different mechanism of action from known anti-tumor compounds.

b. Elucidate the mechanism of action of the drug

In this problem you will be calculating enthalpy changesforN2 . Do not assume constant values of heat capacity. Use a reference state o fT = 25 ̊C and 1 atm pressureto set H = 0 kJ/mol.

a.What is the change in enthalpy thereference state to400 ̊C?

b.What is the change in enthalpy from 800 ̊C to 400 ̊C? In addition, what is the value for enthalpyat 800 ̊C?

c.If the reference state for N2was changed to 100 ̊C, would your answer for part (b) change? If so, what would the change be?
