The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest "number of teens that have heard of a fax machine", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
For this case we want this probability:
Part b
For this case we want this probability:
And adding the values we got:

Answer:
B
Step-by-step explanation:
So first I solved for y. The angle boc and cod together have to be 180 degrees so I subtracted 180 from 45 and then divided by 5. I got 27. Then since I knew what y was I could solve x. Since 5 times 27 is 135. I just plugged in 22 and 23 and realized it had to be 22.
