Question

A number is randomly selected from { 15, 16, 17, 18, 19, 20}.

Answer 1

The answer is B. because it says less than or equal to. so that means any number less than the number stated in this case it is 16. any number in the array of numbers less than the selected number or 16 which in this case is 16. :)

Answer 2

Answer:

C) 2/3

Step-by-step explanation:

Given:  { 15, 16, 17, 18, 19, 20} = 6

Event A is represents the number picked is less than or equal to 16.

Favorable outcomes = { 15, 16} = 2

Probability = The number of favorable outcomes/ The total number of possible outcomes.

Here the total number of outcomes = 6 and the number of favorable outcomes = 2

The probability of getting less than or equal to 16 P(A) = 2/6

Now we have to find the probability of complement event A.

P(A') = 1 - P(A)

= 1- 2/6

= (6 - 2)/6

= 4/6

When we simplify, we get 2/3

Therefore, the probability of complement of event A, P(A') = 2/3

Answer: C) 2/3

Hope this will helpful.

Thank you.
