Question
Solution 1
To calculate the probability of getting 12 heads in 20 attempts from a fair coin, we can use the binomial probability formula, which is:
P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k))
where:
P(X=k) is the probability of k successes in n trials
C(n, k) is the combination of n items taken k at a time
