Hi,

Note: The probability of x successes in n trials is: 

P = nCx* p%5Ex%2Aq%5E%28n-x%29 where p and q are the probabilities of success and failure respectively. In this case p=5/8 & q= 3/8 

nCx = n%21%2F%28x%21%28n-x%29%21%29

For Ex:

P(3) = 20%285%2F8%29%5E3%2A%283%2F8%29%5E3 = .2575

p(≥3) = P(3)+P(4)+P(5)+P(6)= .8535
