Question

A spinner has 5 equal sections numbered 1 to 5. What is the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3?

HELPPPP!!!

Answer 1

0.6

Explanation:

Given that the spinner has 5 equal sections numbered 1 to 5.

• Total Sample Space, n(S)=5

Multiples of 2 in 1 to 5 are: {2,4}

Number less than than 3 are:{1,2}

Since we are required to find the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3, we take the union of both sets.

{2,4}
`\cup` {1,2} ={1,2,4}

Number of Outcomes=3

Therefore,

Probability of the spinner stopping on a number that is a multiple of 2 or is less than 3
`=(3)/(5)=0.6`
