Question 1164485: A corporation has just received new machinery that must be installed and checked before it becomes operational.The company table shows a manager's probability assessment for the number of days required before the machinery becomes operational.
Number of days 3 4 5 6 7
Probability 0.08 0.24 0.41 0.20 0.07
Let a be event "it will be more than 4 days before he machinery becomes operational" and let B be the event "it will be less than 6 days before the machinery becomes available"
a)find the probability of event A
b)find the probability of event B
C)find the probability of the complement of event A
D)find the probability of intersection of event A and B
E)find the probability of the union of event A and B

There is no event A because you described event a. So even if I was of a mind to answer more than one question in this post, I could not. Part b is P(3) + P(4) + P(5). You can do your own arithmetic.
