What is the probability?

Question

The probability that it will snow on the last day of January is 85%. If the probability remains the same for the first eight days of February, what is the probability that it will snow at least five of those days in February?

Answer 1

Sounds like a binomial distribution (a series of Bernoulli trials where the probability of success is always the same). In that case, p = .85 , trials = 8, number of successes 5 or more. = 1 - .0214 or .9786
