With 3 coin tosses, the possible outcomes are:
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
There are 8 possible outcomes and 3 of them have 2 heads. Thus:
probability = 3/8 (= 0.375)

How many times would a coin have to show heads in 50 tosses to show an experimental probability of 20 percent more than the theoretical probability of getting heads?
Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
If a fair coin is tossed ten times what is the probability of getting five heads?
