1) No, 8.0 is the correct answer.

2) a strange and unlikely probability distribution. But lets go with the stated parameters. It states that ZERO percent of the population loses less than 6 lbs OR more than 12 lbs, but exactly evenly distributed between 6 and 12. The denominator for your probability questions will be 6. Soooooo.
1) P(10 or more) = 2/6 = .333
2) P(8 to 11) = 3/6 = .500
3) P(9 to 12) = 3/6 = .500


Find the mean, u, for the binomial distribution whch has the state vlaues of n and p. Round answer to the nearest tenth.

n = 40; p = .2

is u = 80 correct
