About 13% of the population is nervous around strangers. If two people are randomly selected, what is the probability that both are nervous around strangers? What is the probability at least one is nervous around strangers?

Solution

P(nervous around stranger)=0.07

(a)P(Both will be nervous around stranger)=P(nervous around stranger)*P(nervous around stranger)

=0.07*0.07=0.0049

(B) P(atleast one will be nervous)=1-P(none will be nercvous)

=1-0.93*0.93=0.1351
