Answer: The answer is 2k-13 because I just did it.And i'm very good at math.
Step-by-step explanation:
Answer:
(a) Hypergeometric distribution
(b) 0.785384...
Step-by-step explanation:
(a) looking at the question, we see that
, suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose
if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:

Answer:
a. 0.43*125=
53.75
b. this is a little harder we need to find what the conversane is for ec to us
ec 0.43= 1 tt so
6.3*0.43
2.71 ec=1 us
850.94 divided by 2.71
314 us
Hope This Helps!!!
