Heya

Here is ur answer

========================

Given :-

Tickets are drawn at random from 1 -20

Question :- probability of getting multiple of 3 and 5

__________

Probability = no. Of favourable outcomes / no. Total possible outcomes.

Here

Possible outcomes = 1-20 = 20.

Favourable outcomes =

multiples of 3 from 1-20 are :-

3 ,6,9,12,15,18

Multiples of 5 from 1-20 are :-

5,10,15,20

➡ 15 is the only multiple of both 3 and 5 from 1-20

So ,

Favourable outcomes = 1

Hence

Probability = 1/20
