Answer:
a. 74.63%
b. 33.63%
c. 87.67%
Step-by-step explanation:
If 59% (0.59) of the workers are married, then It means (100-59 = 41%) of the workers are not married.
If 43% (0.43) of the workers are College graduates, then it means (100-43= 57%) of the workers are not college graduates.
If 1/3 of college graduates are married, it means portion of graduate that are married = 1/3 * 43% = 1/3 * 0.43 = 0.1433.
For question a, Probability that the worker is neither married nor a college graduate becomes:
= (probability of not married) + (probability of not a graduate) - (probability of not married * not a graduate)
= 0.41 + 0.57 - (0.41*0.57) = 0.98 - 0.2337
= 0.7463 = 74.63%
For question b, probability that the worker is married but not a college graduate becomes:
=(probability of married) * (probability of not a graduate.)
= 0.59 * 0.57
= 0.3363 = 33.63%
For question c, probability that the worker is either married or a college graduate becomes:
=probability of marriage + probability of graduate - (probability of married and graduate)
= 0.59 + 0.43 - (0.1433)
= 0.8767. = 87.67%
The total surface area of a cylinder with 5cm height and radius 2cm is :
28π cm²
<h3>What is cylinder?</h3>
One of the most fundamental curvilinear geometric shapes, the cylinder has historically been thought of as a three-dimensional solid. Geometrically speaking, it has been referred to as a circle-based prism.
Analysis:
The total surface area of a cylinder is : 2πrh + 2π
where radius = 2cm , Hight = 5cm
Total surface area = 2 x π x 2 x 5 + 2 x π x 2 x 2
= 20π + 8π = 28π cm2
In conclusion, the total surface area of the cylinder is 28π cm2.
