Question

a coin is tossed 3 times find probability of getting at least 2 heads , exactly 2 heads , atmost 1 head and getting more heads then tails ​

Answer 1

Answer:

sample space: (HHH,  HHT,  HTH, THH, HTT,  THT,  TTH, TTT)

P of getting at least two heads =      4/8

                                                    = 1/2

P of getting exactly two heads =  3/8

P of getting atmost one head  = 4/8

                                                   = 1/2

P of getting more head then tails =  4/8

                                                        = 1/2

Hope this helps!
