no X are yoused tails is : so, - is : one 13 now, the probabilit coins of getting cohen 5 fair xxx = 0.03125 atleast the probability of getting (-0.03125 ) = 0.96875 ~ 0.969 Hence option (A) 1.0.969 is correctcams). 2) When two fair coin are tossed, the possible events {HH, HT, TH, TT) Here H means Head and ways that either or B probability that either A or B occurs 4 Hence (c) is correct are T means Tail. Now, the coo OCCUYS . that say are : HT, TH, HH so, the is : 3 CAW). 24
