There are 25 tickets numbered from 1 to 25. A ticket is drawn at random. Find the probability that the number of that ticket is either a multiple of 2 or multiple of 3.

Answer

N/a

Explanation

Here `n(S)=.^(25)C_(1)=25`
Let `E=` event of getting a ticket whose number is either a multiple of 2 or multiple of 3
`={2,3,4,5,8,9,10,12,14,15,16,18,20,21,22,24}`
`implies n(E)=16`
`:. P(E)=(n(E))/(n(S))=16/25`
