Two cards are drawn successively with replacement from a well-shuffled deck of 52 cards. Let X denote the random variable of number of aces obtained in the two drawn cards. Then `P(X=1)+P(X=2)` equals `(5k)/169`. The value of k is______________.

Text Solution

Verified by Experts

The correct Answer is:
5
`P(X=2)=(4/52)^(2)`
