Cards are drawn one by one at random from a well suffied full pack of 52 playing card until 2 aces are obtained for the first time. Then prove that probability that exactly n cards are drawn, is `(n-1(52-n)(51-n))/(50xx49xx17xx13),where 2ltnle50.`

Cards are drawn one at random from a well shuffled full pack of 52 playing cards until 2 aces are obtained for the first time. If N is the number of cards required to the drawn, then show that P ,{N=n}=((n-1)(52-n)(51-n))/(50xx49xx17xx13),w h e r e2

Cards are drawn one-by-one at random from a well-shuffled pack of 52 playing cards until 2 aces are obtained from the first time. The probability that 18 draws are obtained for this is a. 3//34 b. 17//455 c. 561//15925 d. none of these
