Answer:
a) 0.01111
b) 0.4679
c) 0.33747
Step-by-step explanation:
We are given the following in the question:
The number of accidents per week can be treated as a Poisson distribution.
Mean number of accidents per week = 4.5

Formula:
a) No accidents occur in one week.
b) 5 or more accidents occur in a week.

c) One accident occurs today.
The mean number of accidents per day is given by

F(x) = 2x^2 - 4x - 3
g(x) = 2x^2 - 16
f(x) + g(x)
2x^2 - 4x - 3 + 2x^2 - 16
4x^2 - 4x - 19
Probability =
(number of possible ways to succeed)
divided by
(total number of possible outcomes) .
Number of ways to succeed = 2 (pick the 'A' or the 'L')
Total number of possible outcomes = 5 (the cards on the table) .
Probability of success = 2/5 = 40% .
