<PRE><B>Question 1061335</B>
we use the binomial probability formula
:
probability(p) = 0.49, (1-p) = (1-0.49) = q = 0.51, n = 11, r = 8
:
P ( 8 successes ) = 11C8 * (0.49)^8 * (0.51)^(11-8)
:
note that 11C8 = 11! / ( 8! * (11-8)!
:
P ( 8 successes ) = 165 * 0.0033 * 0.1327 = 0.0723 approximately 0.07 or 7%
