I have two questions in the area of probability related to a development course being taken, but I never took this stuff back in college and don't know where to begin! Any help would be oh so appreciated.
Here they are:
1. "Fifty people answer calls in a call centre. The pobability that any individual will be absent is 0.02. What is the probability that no more than two people will be absent on a typical day?"
-Now, I do remember that the probability of exactly two independent events A and B happening is figured by multiplying the P(A) by the P(B). But the "no more than" is what has me confused. Where do I start?
2. On average, five calls per hour will not be answered within the target time. What is the probability of:
i)six calls not being answered within the target time during one hour?
ii) four calls not being answered within the target time during one hour?
iii)a total of ten calls not being answered within the target time during a two-hour period?
-This one has me totally lost from the beginning.
Any help would be great. Thanks!
