Each of five contestants competing in a quiz are asked 10 quick-fire questions, and their answers may be correct or incorrect with equal probability. The score of each contestant depends on the number of correct answers. What is the probability that   (a) all contestants get a different score? (b) exactly 2 of them get the same score? (c) exactly 3 of them get the same score?

Answers must be in 4 decimals If the probabilities that a computer technician will repair 3,4,5,6,7, or 8 or more laptops on any given workday are 0.12, 0.19, 0.28, 0.24, 0.10, and 0.07, respectively, what is the probability that he will service more than 5 laptops on his next day at work?

In a family with three children what is the probability that the oldest two children are girls assuming that the probability of boy being born is same as that of girl being born

Suppose that Stephen makes 95% of his free throws. Assume that late in a basketball game, he is fouled and is awarded two shots. (a) What is the probability that he will make both shots? (b) What is the probability that he will make at least one shot? (c) What is the probability that he will miss both shots? (d) Late in a basketball game, a team often intentionally fouls an opposing player in order to stop the game clock. The usual strategy is to intentionally foul the other team's worst free- throw shooter. Assume that Stephen's team's center makes 57% of his free-throw shots. Calculate the probabilities for the center as shown in parts (a), (b), and (c). Assume as in parts (a), (b), and (c) that two shots will be awarded. P(center makes two shots) = P(center makes at least one shot) = P(center misses both shots) =
