Question: 1. Ten numbers are produced by a random number generator. What is the probability four or more are less than or equal to 0.63?
2. A player rolls a pair of dice five times. She scores a "hit" on any throw if she gets a 6 or 7. She wins iff she scores an odd number of hits in the five throws. What is the probability a player wins on any sequence of five throws? Suppose she plays the game 20 successive times. What is the probability she wins at least 10 times? What is the probability she wins more than half the time?
