Problem #5: A 2-digit code is obtained as follows. The first digit is a random integer from 0 to 9 (inclusive) and the seconddigit is a random integer from 0 to 7 (inclusive). Let E be the event that the first digit is even, let F be the eventthat the second digit is odd, and let G be the event that the product of the two digits is odd. (Note that 0 is even.)Find the number of outcomes in the following events.(a) FOG(b) EN F(c) EUF(d) EN GC

Recently, Hector ran for president of the local school board. Of those who voted in the election, 80% had a high school diploma, and the other 20% did not. Hector got 65% of the vote of those with high school diplomas, while he got only 25% of the vote of those without high school diplomas. Let D denote the event that a randomly chosen voter (in the school board election) had a high school diploma and D denote the event that a randomly chosen voter did not have a high school diploma. Let H denote the event that a randomly chosen voter voted for Hector and H denote the event that a randomly chosen voter did not vote for Hector. Fill in the probabilities to complete the tree diagram below, and then answer the question that follows. Do not round any of your responses. (If necessary, consult a list of formulas.)

Urn A has four red balls and two white balls, and urn B has three red balls and four white balls. A fair coin is tossed. If it lands heads up, a ball is drawn from urn A; otherwise, a ball is drawn from urn B. Compute (a) the probability a red ball is drawn (b) the probability that thecoin landed heads up, if it is known that a red ball was drawn.
Consider a six-sided fair die (the six faces are labeled 1 to 6). If the fair die is tossed two times and "3" shows up both times, the probability of "3" on the third trial is much larger than any other outcome. much smaller than any other outcome. the same as any other outcome. not able to be determined before the die is tossed.
An experiment consists of rolling a fair die twice. Let A be the event that in the second roll the die lands 1, 2, or 5; B be the event that in the second roll the die lands 4, 5, or 6; and C be the event that the sum of the two outcomes from the two rolls is 9. Please choose the correct answer:
Step 4: Now calculate the probabilities P(AC) and P((A ∩ B)C) by first listing the simple events in AC and (A ∩ B)C. There are five simple events E1, E2, ..., E5. The complement of A is the collection of simple events that are not in A. We are given that A = {E2, E3}, so AC consists of the following event(s). (Select all that apply.) E1 E2 E3 E4 E5 We previously found that A ∩ B = {E2}. Therefore, the complement (A ∩ B)C includes the following event(s). (Select all that apply.) E1 E2 E3 E4 E5
Let A and B be two events with P(A and Bc) = 1. Find P(B). Recall that Bc denotes the complement of the event B.

2. A group of three undergraduate and six graduate students are available to fill certain student government posts. If four students are randomly chosen from this group, find the probability that exactly two undergraduates will be among the four chosen. [Hint: How many ways are there to fill the posts? How many ways satisfy the condition of having exactly TWO undergraduates selected AND hav- ing exactly two graduates selected?]
A letter is first chosen at random from the word SAMPLE, and then the next letter is chosen at random from the word SET. The two letters chosen are recorded. A is the event that the first letter chosen is a vowel, and B is the event that the second letter chosen is a vowel, and C is the event that the two letters chosen are the same. Find n(C'n (A U B)).
