clocks are defective. Suppose that you choose 8 clocks at random. What
is the probability that 2 or less of the clocks are defective.
Your Answer:
f(x)= n!/x!(n-x)!p^x(1-p)^(n-x)
f(x)=8!/2!(8-2)!^.13^2(1-.13)^(8-2)= .205
f(x)=8!/1!(8-1)^.13^1(1-.13)^(8-1)= .392
f(x)=8!/0!(8-0)^.13^0(1-.13)^(8-0)= .328
.205+.392+.328= .925
