    So, I need a little bit of help on my homework for this one question.
    Part (i) of the question asks me to determine the probability of [7, 10] which I worked out to be 0.4804.
    But (ii) then asks me: Hence calculate the probability that, on each of three consecutive days, Candice will receive a total of at least 7 but at most 10 phone calls and emails.
    I wasn't quite sure how to approach this one and I was wondering if anyone would be able to explain to me?

    How is this Poisson? Using [7, 10] means an interval over the reals, not the integers. Also, what's the mean of the poisson distribution? You need to tell us this information in the future.

    In this case, the answer is straightfroward. Part (ii) is asking you for the probability of (7-10) on the first day, (7-10) on the second day and (7-10) on the third day. The probability of this is the probability of (7-10) occurring multiplied by the probability of (7-10) occurring multiplied by (7-10) occurring. Think probability tree. i.e: your answer to part (i) cubed.

    It's fine. As long as you do it in the future.

    Do you understand my answer, though?

    think simpler, poisson is S2

    WJEC put Poisson in S1 for us
