About 1919 % of the population of a large country is nervous around strangersnervous around strangers. if two people are randomly selected, what is the probability both are nervous around strangersnervous around strangers ? what is the probability at least one is nervous around strangersnervous around strangers ?

Probability that a person is math phobic = 19% = 19/100

a) the probability that both are nervous around strangers

P (A)

= 19/100 * 19/100

= 361/10000

= 0.0361

b) The probability that both are not nervous around strangers

P (B) = 81/100 * 81/100

= 0.6561

The probability that at least one person is nervous around strangers i. e. P' (B) = 1 - P (B)

= 1 - 0.651

= 0.3439
