Probability

class consists of 100 students, 25 of them are girls and 75 boys; 20 of them are rich and remaining poor; 40 of
them are fair complexioned. The probability of selecting a fair complexioned rich girl is

$P(Girl) = \frac{25}{100} = \frac14$

$P(Rich) = \frac{20}{100} = \frac15$

$P(Fair\ complexioned) = \frac{40}{100} = \frac25$

Now, find $P(Girl\ \cap\ Rich\ \cap\ Fair\ Complexioned)$
