what is the probabaility of getting 50 heads while tossing 99 coins?
Read Solution (Total 3)
-
- Total possibilities = 2 ^ 99
50 heads on 99 coins can happen in 99 C 50 ways
Required Probability = 99 C 50
---------
2 ^ 99 - 11 years agoHelpfull: Yes(15) No(7)
- total no of possibilities=2^99
probabilty to get 50 heads for 99 coins means remainng 49 are tails....
arranging of 50 heads and 49 tails in 99 coins gives as ............
99!/(50!*49!).....
there4 required probability is 99C50/2^99 - 11 years agoHelpfull: Yes(8) No(0)
- 50/2^99
toal condition 2^99 but coin are same so favourable condition is 50 - 11 years agoHelpfull: Yes(2) No(2)
