Question

What is the probability of the complement of spinning an even number by using the spinner below

the answer is NOT 3/8​

Answer 1

5/8

Explanation:

Answer 2

`(5)/(8)`

Explanation:

We first need probability of spinning an even number BUT its complement.

THe complement is basically all outcomes THAT ARE NOT THE EVENT.

So, we find the probability of even number then we subtract that probability from 1. Because:

P(event) + P(complement of event) = 1

Now,

Looking at the spinner, it has total 8 divisions.

The number of even numbers is 3 (2, 4, and 2)

So

P(even) = 3/8

But we need its complement, so we have:

P(even) + P(complement of even) = 1

3/8 + P(complement of even) = 1

P(complement of even) = 1 - 3/8 = 5/8

The answer is
`(5)/(8)`
