Solution:
Total no. of incoming calls, n = 20
Probability of incoming calls with fax messages, p = 20% = 0.20
q = (1 - p) = 0.80
(a) Now, let 'r' be the no. of incoming calls with fax messages, then by Binomial distribution of probability mass function:
P(X = r) = 
(1)
P(X ≤ 7) = 
P(X ≤ 7) = 0.0115 +........+ 0.0545
Total no. of incoming calls, n = 20
Probability of incoming calls with fax messages, p = 20% = 0.20
q = (1 - p) = 0.80
(a) Now, let 'r' be the no. of incoming calls with fax messages, then by Binomial distribution of probability mass function:
P(X = r) = (1)
P(X ≤ 7) =
P(X ≤ 7) = 0.0115 + 0.0545
P(X ≤ 7) = 0.9689
probability that atmost 7 of the calls are with fax is 0.9689
Answer:
The haunting story centers on twelve-year-old Jonas, who lives in a seemingly ideal, if colorless, world of conformity and contentment. Not until he is given his life assignment as the Receiver of Memory does he begin to understand the dark, complex secrets behind his fragile community.

Explanation:
Independence Day is a federal holiday. If July 4 is a Saturday, it is observed on Friday, July 3. If July 4 is a Sunday, it is observed on Monday, July 5. Government offices and schools are closed. Some businesses may be closed as well. In some years, many employees use a proportion of their vacation days to create a long weekend. This can cause congestion in some places, particularly towards popular holiday destinations.There are many public events, parades, shows and fireworks displays. This may cause local disruption to traffic. Public transit systems do not usually operate on their regular timetables though.
