Could you help me to solve this issue a),B) and C)

Find the indicated probabilities using the geometricdistribution, the Poissondistribution, or the binomial distribution. Then determine if the events are unusual. Ifconvenient, use the appropriate probability table or technology to find the probabilities.

The mean number of births per minute in a country in a recent year was about seven. Find the probability that the number of births in any given minute is(a) exactly four, (b) at least four, and(c) more than four.

(a) P(exactly four)=

nothing

(Round to four decimal places asneeded.)
