One ticket is selected at random from 10...

One ticket is selected at random from 100 tickets numbered `00,01,02, …, 99.` Suppose A and B are the sum and product of the digit found on the ticket, respectively. Then `P((A=7)//(B=0))` is given by

Text Solution

Verified by Experts

set A= `{ 8,17, 26, 35,44}`
set B= `{00,01,.......09,10,20,30,40}`
`P(A/B)= (P(A nn B))/(P(B))`
`= (1/50)/(14/50)`
`= 1/14`
option 1 is correct
