Answer: 0.3741
Step-by-step explanation:
Poison probability ;
P(x) = [U(^x) e(^-U)] ÷ x!
Where U = mean
Note: e = exponential symbol
Number of checks that year = 171
Number of days in a year = 365
U = 171/365 = 0.468
Average checks per day = 0.4685
Probability that at least one check was written per day is can be calculated by;
P(not 0) = 1 - P(0)
Therefore,
P(x) = [U(^x) e(^-U)] ÷ x!
P(0) = [ 0.4685^0 * e^-0.4685] ÷ 0!
P(0) = [ 1 * 0.6259] ÷ 1
P(0) = 0.6259
Therefore,
P(not 0) = 1 - 0.6259 = 0.3741

Answer:
yellow area ≈ 48.3 cm²
Step-by-step explanation:
The area of the yellow region is the difference between the area of a square with side length 15 cm and the area of a quarter circle with radius 15 cm. It is helpful to know the formulas for area for a square and a circle.
Area of the square = s² = (15 cm)² = 225 cm²
The area of the full circle is ...
Area of circle = πr² = π(15 cm)² = 225π cm²
Then the area of 1/4 of that circle will be ...
Area of quarter circle = (225π cm²)/4 = 56.25π cm²
--
The difference of these areas is the yellow area:
yellow area = 225 cm² - 56.25π cm² ≈ 48.2854 cm²
yellow area ≈ 48.3 cm²
