Given the normally distributed variable X with mean 18 and standard deviation 2.5, find
(a) P(X \leq 15) :
(b) the value of k such that P(X (c) the value of k such that P(X>k)=0.1814;
(d) P(17

i think its a and d

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
