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... Answer by ewatrrr(24785) (Show Source):
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)
