If three square are selected at random from chess board. then the probability that they form the letter 'L' is (a) `196/(64C_3)` (b) `49/(64C_3)` (c) `36/(64C_3)` (d) `98/(64C_3)`

If three squares of dimension 1xx1 are selcted at random from the chess board , then the probability that they form the letter L is

If nine squares are chosen at random on a chess board,find the probability that they form a square of size 3xx3 .

If two of the 64 squares are chosen at random on a chess board,the probability that they have a side in common is

A box contains 10 good articles and 6 defective articles. One item is drawn at random. the probability that it is either good or has a defect, is a. 64/64 b. 49/64 c. 40/64 d. 24/64

A fair coin is tossed 10 xx.Then the probability that two heads do not occur consecutively is 7/64 b.1/8 c.9/16 d.9/64

The probability of getting at least 2 heads, when an unbiased coin is tossed 6 xx is (A)(63)/(64) (B) (57)/(64) (C) (7)/(64) (D) (37)/(64)
