110 independent experiments has been conducted. In each experiment event X can realise with probability 0.035. Please calculate probability that event X realises less than 4 times.
Added by John B.
Step 1
We can use the binomial distribution formula for this: P(X=k) = (n choose k) * p^k * (1-p)^(n-k) where n is the number of experiments (110), p is the probability of X occurring in a single experiment (0.035), and k is the number of times X occurs. For Show more…

Consider 13 independent experiments. The probability of event A in each experiment is 0.8. Find the probability that event A occurs 1) exactly 10 times; 2) more than 10 times.
