Question 868737: A marksman can hit the center of a target with a probability of p = 0.4. Find the probability that out of 10 trials, the marksman can hit the center:
a. exactly 6 times
b. at most 3 times
c. Find the mean and standard deviation for this situation.
Would you be kind enough to include the solution? Thank you...

You can put this solution on YOUR website!
p(hitcenter) = .4, n = 10
a) P(x=6)= binompdf(10, .4, 6)
b) P( x ≤ 3) = binomcdf(10, .4, 3)
c) mean = 4 and SD = sqrt(4*.6)
