1. Another couple is only willing to have 5 children, but they also want to have a boy and a girl, and they too will stop as soon as they have one of each. What is the expted number of children they will have?

2. Out of a bag with 10 red marbles, 7 blue marbles and 16 orange marbles, what is the expected number of times a person will randomly draw out either a red or blue marble on 10 draws?

1. A married couple decides that they will continue to have children until they have 3 girls. It is assumed that having a boy or a girl is equally likely. a. What is the probability that the couple has 5 children until they have 3 girls? (specify the variable and what distribution is being used) b. How many children does this couple expect to have until they have girls? (specify the variable and what distribution is being used)

Suppose Bob is only willing to buy a bike seat if he can also buy a bike seat cover to go with it, i.e. Bob needs an equal number of bike seats and bike seat covers. Bob has $100 in income. a. (10 points) Suppose bike seat covers cost $1 and bike seats cost $19. How many of each will Bob buy? Discuss and illustrate graphically. b. (10 points) Suppose the price of bike seats increases to $49. How will...

A couple plans to have children until they get a girl, but they agree they will not have more than three children, even if all are boys. Assume that the probability of having a girl is 52.00 %. a) Create a probability model for the number of children they'll have. b) Find the expected number of children. c) Find the expected number of boys they'll have.

A couple wants to have 2 boys and 2 girls. They will continue to have children until they have reached the goal.  Assuming that the probability that they have 54% chance to have a boy and 46% chance to have a girl in every pregnancy. No twin or more are possible.  Assuming that their goal is possible and has been fulfilled today! Create at least four hypotheses based on the data file provided! 1) Use a different test for each...

A couple decides to have children. Both have the same genotype: they are fully heterozygous at the following loci: albino (Aa), MN blood group (L^M L^N), and Rh factor (Rh+/Rh-). The Rh+ allele is dominant to the Rh- allele. Assuming that the genes encoding these traits are located on different autosomes, determine the excepted genotypic and phenotypic of their ratios in their offspring.

a couple intends to have three children. assume (for some reason) that having a boy or a girl are not equally likely events, and that p(boy)=.4 and p(girl)=.6 for each delivery also assume the births are independent of each other (a. what is the sample space of this experiment? Use a tree diagram and label the branches with their corresponding probabilities. Then make a table including all outcomes from the experiment with their associated probabilities. (b. Find the probability that...

researchers at a university studied children born with an infection called roseola. the children also have the causative herpesvirus inserted into their chrome osmoses. At least one parent of each child had the virus in a chromosome of a sampled hair cell. How did the children like;y become infected? and What does the transmission of the viral DNA from generation to generation reveal about the structure of DNA and its replication?

1). If a couple has two children, what is the probability that they are both girls assuming that the older one is a girl? 2). Suppose that we have two dice, the first one being a regular die, and the second weighted so that half the time it rolls a 1, and half the time it rolls a 2 (it never rolls anything else). If we choose one of these dice at random, and roll a 1, what’s the probability...

Assume another product line is also being considered – bookshelves. Only use this information for the questions listed directly below.  Higher skilled workers would be required which will result in paying them $15 per hour.  Additional MOH costs for the year will be $150,000. These costs will be in addition to the costs already being incurred. These costs are due to the additional product line and also related to the current product lines for additional production abilities. The...
