1.

Suppose you perform an experiment that consists of rolling two dice and

recording their sum.

a. What is the sample space of this experiment?

b. Find the probability that the sum is either even or more than 9.

c. Find the probability that the sum is odd and a multiple of 3.

d. Find the expected sum.

2.

When Fernando took MAT 257 last semester, he got the same exact score, 85%, in both Test 1 and Test 2. If the class mean and standard deviation for Test 1 were 86% and 4%, respectively, while the class means to score and standard deviation for Test 2 were 86% and 5%, respectively, in which test did Fernando perform relatively better? Explain.

11.) An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. Assuming each simple event is as likely as any other, find the probability that the sum of the dots is greater than 2. The probability that the sum of the dots is greater than 2 is 12.) An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. Find the probability of the sum...

An experiment consists of rolling six-sided dice twice. &

An experiment consists of rolling six-sided dice twice. (10) List the sample space for this experiment. Find the probability distribution for this experiment where x represents the number of even numbers in the 2 rolls. Find the mean of the probability distribution. Find the standard deviation of the probability distribution. Would it be unusual to get 2 even numbers? Why or why not? (show your work)

. Dice rolling: In c++Write a program that simulates the rolling of two dice. The sum of the two values should then be calculated. [Note: Each die can show an integer value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums.] The following table shows the 36 possible combinations of the two dice. Your program should...

Consider the game consisting of rolling a pair of fair 6-sided dice and recording the sum. It will cost you $1 to play the game. If the sumis less than 5, then you will win $3. However, you do not get your $1 back so your profit is $2. If you roll a sum of exactly8, thenyou will win $4. However, you do not get your $1 back so your profit is $3. Otherwise, you lose your $1.
