Based on this assumption, we can state that the expected relative frequency of an outcome is equal to the probability of that outcome. WebKen was skeptical of his friend's story, however, he told Alan to flip the coin 100 times and to record how many flips resulted with heads.

WebSay with ten flips, you wanted the probability of at least 9 heads. With your generalization it would be: P (X>=9) = 1 - ∑ {k=0 to n-1} P (X=k) But this might have you calculate 9 probabilities (0,...,8), when it might be easier to calculate P (X=9) + P (X=10).
