Web(b) A comment is in order here. The question asks “What is the value of P[X1 > 7] the probability that one outcome exceeds 7”. The probability that X1 exceeds 7 is not, in general, the same as the probability that some Xi exceeds 7, however in this problem, the Xi are iid, so these two quantities are equal. P [X1 ≥ 7] = 1 −P [X1 ≤ 7] (2) WebOn a higher level, if we assess a succession of numbers, x 1, x 2, x 3, . . . , x k, we can record the sum of these numbers in the following way: x 1 + x 2 + x 3 + . . . + x k. A simpler method of representing this is to use the term x n to denote the general term of the sequence, as follows:
