From a well shuffled deck of cards, `2` cards are drawn with replacement. If `x` represent numbers of time ace coming, then the value of `P(x=1)+P(x=2)` is (a) `(25)/(169)` (b) `(24)/(169)` (c) `(49)/(169)` (d) `(23)/(169)`

Suppose that two cards are drawn at random from a deck of cards. Let X be the number of aces obtained. Then the value of E(X) is

Suppose that two cards are drawn at random from a deck of cards. Let X be the number of aces obtained. Then the value of E(X) is(A) (37)/(221) (B) 5/(13) (C) 1/(13) (D) 2/(13)

From a well-shuffled deck of 52 cards, one card is drawn. Find the probability that the card drawn is : (vi) a card with number between 2 and 9.

Two cards are drawn successively with replacement from a well shuffled deck of 52 cards, then the meanof the number of aces is

Two cards are drawn successively with replacement from a well-shuffled deck of 52 cards . The mean of number of Aces is

A card is drawn at random from a pack of 52 cards. The probability that the drawn card is not an ace is (a) 1/(13) (b) 9/(13) (c) 4/(13) (d) (12)/(13)

Two cards are drawn from a well shuffled deck of 52 playing cards with replacement. The probability that both cards are queen is a. 1/(13)xx1/(13) b. 1/(13)+1/(13) c. 1/(13)xx1/(17) d. 1/(13)xx4/5

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

Two cards are drawn successively with replacement from a well shuffled deck of 52 cards. Find the mean and standard deviation of the number of aces.

Two cards are drawn successively with replacement from a well shuffled pack of 52 cards. Find the probability distribution of the number of aces.
