1. If A1, A2, and Az are three events and P(A, n Az ) = P(A, N A3 ) # 0 butP(A2 N Ay ) = 0, show thatP(at least one A,) = P(A, ) + P(A2 ) + P(A,) – 2P(A, n A2 )2. Suppose that two balanced dice are tossed repeatedly and the sum of theuppermost faces is determined on each toss. What is the probability that weobtaina) A sum of 3 betore we obtain a sum of 7?b) A sum of 4 betore we obtain a sum of 7?

12.) Jar 1 contains 2 orange marbles and 1 green marble. Jar 2 contains 1 orange marble and 2 green marbles. Jar 3 contains 1 orange marble and 1 green marble. Fist a jar will be selected, then one marble will be drawn from that jar. The probabilities of selecting the first, second, or third jar are 1/2, 1/3, and 1/6 respectively. A green marble is drawn. What is the probability that it came from Jar 2? This is a Bayes' Theorem problem.

5. A candy dish contains 2 red (R) and 4 yellow (Y) candies. You close your eyes, select two candies from the dish (without replacement), and record their colors. Use general multiplication rule and special addition rule to find the following probabilities. a. The probability that the first selected candy will be red and the second selected candy will be yellow is b. The probability that two selected candies will be of different colors_ One is red, another one is yellow c. Probability that two selected candies will be of the same color_ Both are red or both are yellow Assuming that the event "The first selected candy will be red and the second selected candy will be yellow "is denoted by A, the event "Two selected candies will be of different colors" is denoted by B, and the event "Two selected candies will be of the same color" is denoted by C, show your work in finding P(A), P(B), and P(C) in the questions a, b, and c.

Hanna has a pair of 8-sided dice and if it rolls to 4,6 or 10 marie wins, if it rolls 9 or 13, marie loses For example, in case 7 comes out first, it is a tie so you need to roll it again and get 7 since it was your last number, if you get 7 again on your next few rolls, you win. but if you get 10, you lose what is the probability of marie winning the game? is she at disadvantage based on the rules? explain why or why not using computed probability of winning
