Question

A number is randomly selected from {1, 2, 3, 4, 5, 6, 7, 8, 9, 10).

What is the COMPLEMENT of selecting a number greater than 7?
Enter your answer as a FRACTION.

Answer 1

it is 3/10

Explanation:

1, 2, 3, 4, 5, and 6 are all LESS than 7. 8, 9, and 10 are all GREATER than 7, therefor,
`(3)/(10)` is the complement.

Answer 2

In this case, the complement would be selecting a number less than or equal to 7; the probability of this occurring is
`\boxed{(7)/(10)}.`
