Question

find the mean of the given porobbility distribution the number of golf balls ordered by customers of a pro shop has the following probability distribution x3 6 9 12 15 P(x) 0.14 0.05 0.36 0.35 0.10

Answer 1

sum of x values = 45

3*.14 + 6*.05 + 9*.36 + 12*.35 + 15*.1 = 9.66

9.66/45 = .215

that 6 , .05 point looks like either a typo or an outlier
