Question

Suppose you toss a coin 100 times and get 66 heads and 34 tails. Based on these results, what is the probability that the next flip resuming a tail

Answer 1

Let the number of tails in the previous trials be $x=34$

Let the total number of trials be $n=100$

The number of heads in the previous trials is $n-x=100-34=66$

The probability that the next flip will be a tail is given as,

$p(tail)={x\over n}={34\over100}=0.34$
