Question

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 drawncards. Then P (X=1 )+P (X=2 ) equals:

Accepted Answer

Correct answer: D. (d) JEE Main 2019 X= number of aces drawn ∴P (X=1 )+P (X=2 ) =( 452 4852+ 4852 452)+( 452 452) = 24169+ 1169= 25169
