two players each flip a fair coin. the probability that they get the same result can be expressed as a fraction a/b, what is such fraction?



Answer :

If the probability that two player get the same result is fraction a/b , then such fraction is 1/2 .

In the question ,

it is given that ,

the two players flip a fair coin .

So , the total number of outcomes will be = HH , TT , HT , TH = 4 .

the required event that both will get the same result is = HH , TT = 2

the probability is = (favorable outcomes)/(total outcomes)

So , the required probability is = 2/4

simplifying the fraction ,

we get ,

= 1/2 .

Therefore , the fraction a/b is 1/2 .
