A population consists of 500 elements. We want to draw a simple random sample of 50 elements from this population. On the first selection, the probability of an element being selected is.

a. 0.100.
b. 0.010.
c. 0.001.
d. 0.002.

correct option is A

0.100

Step-by-step explanation:

Given that

population = 500 elements.

To draw a simple random sample of 50 elements from this population. On the first selection

The probability = 50/500 = 0.1

The probability of an element being selected is 0.100

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
