Area of trapezoid = (B1 + B2)h/2
B1 = 15 in. + 4 in. + 6 in. = 25 in.
B2 = 15 in.
h = 7 in.
Area = (25 in. + 15 in.)(7 in.)/2 = 140 in.^2

Answer:
21.77% probability that the antenna will be struck exactly once during this time period.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
In this question:

Find the probability that the antenna will be struck exactly once during this time period.
This is P(X = 1).


21.77% probability that the antenna will be struck exactly once during this time period.
