Two distinct numbers a and b are selected at random from 1,2,3, ... ,50. The probability that their product ab is divisible by 3, is:

Solution

Required probability

$= 1 - (\text{product not divisible by } 3)$

Multiples of $3 = 16$

Not multiple of $3 = 34$

$= 1 - \frac{{}^{34}C_2}{{}^{50}C_2} = \frac{664}{1225}$
