# Fatima and

Given that,

P(FS) = P(Fatima’s selection)

P(FN) = P(Not selecting Fatima)

P(JS) = P(John’s selection)

P(JN) = P(Not selecting John)

We need to find:

i. Both of them will be selected

ii. Only one of them will be selected

iii. None of them will be selected

P(Sboth) = P(Both of them are selected)

Since selection of each person is an independent event their probabilities multiply each other

P(Sone) = P(Only one of them is selected)

P(Sone) = P(only Fatima is selected) + P(only John is selected)

Since selection of each person is an independent event their probabilities multiply each other

P(Snone) = P(None of them are selected)

Since selection of each person is an independent event their probabilities multiply each other

The required probabilities are .
