probability of a computer being ancient = .99
probability of a computer being cutting-edge =.01
probability of two selected computer being old
= .99 x .99
= .98 or 98%
b )
probability of 5 selected computers being old
= .99 x .99 x .99 x .99 x .99
= .95 or 95%
c )
probability that at least one of the five selected computers is cutting-edge
= 1 - probability of 5 selected computers being old
= 1 - .95
= .05
5 %
