A golfer claims that 80% of the time, he will score less than 90 on the golf course he normally plays. Consider his next 10 rounds of golf.

a. What is the probability that he will score lower than 90 on all 10 rounds?

b. What is the probability that he will score lower than 90 on eight or more rounds?

c. What is the probability that he will score lower than 90 on either six or seven rounds?

d. Construct a histogram for this distribution.

e. Suppose that out of the 10 rounds, he scores lower than 90 on five of them. What conclusions can be drawn about the golfer’s claim?
