Assume that you play the following game: • in each round, you roll a fair die twice; • you win a round if at least one of the rolled numbers is 6; • otherwise, you lose a round. (a) What is the probability you win a round? Explain your steps. (b) Assume that you play 20 rounds, and let X be the number of rounds you win. What is the probability you win at most 1 round out of 20? In other words, find P(X ⩽ 1). Explain your steps

Multiply probabilities? A traffic light at an intersection near Jamal's house is red 30 % of the time, green 10 % of the time, and yellow 60 % of the time. Jamal encounters this light in the morning on his way to work and again in the evening on his way home. Is the probability that the light is red both times equal to =×0.30.30.09 . Explain why or why not.
Use the Test for Independence to determine if events A and B are independent. P(A) = 0.7, P(B) = 0.8, P(An B) = 0.56 Select the correct choice below and fill in the answer box(es) to complete your choice. (Type an integer or a decimal.) O A. Events A and B are not independent because P(A U B)= | and P(A) + P(B) - P(An B)= O B. Events A and B are independent because P(An B) = 0.56 and P(A).P(B) = O C. Events A and B are independent because P(A U B)= and P(A) + P(B)- P(An B) = O D. Events A and B are not independent because P(An B) = 0.56 and P(A) P(B) =.
