Hi
Note: The probability of x successes in n trials is: 
P = nCx* {{{p^x*q^(n-x)}}} where p and q are the probabilities of success and failure respectively. 
In this case p & q are = 1/2 or .5
nCx = {{{n!/(x!(n-x)!)}}}
P( less than 5 correct) = P(4correct)+ P(3)+  P(two)+  P(one)+  P(none)
                          0.041660 +.013890 + .003200 + .000460 + .000030
P( less than 5 correct)= .05923
