There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner is spun one time, what is the probability that the result is a multiple of 2 and a multiple of 5?

Answer 1

THe only number that is a multiple of 2 AND a multiple of 5 is the number 10
So you seek the probability of the spinner landing on the number 10
there is a one in 10 chance that this happens
1/10

Answer 2

wrong

Answer 3

The first one is right

Multiples of 2:
2, 4, 6, 8, 10

Multiples of 5:
5, 10

Multiple of 2 AND multiple of 5:
the intersection of the sets
10

Number of acceptable values: 1

Number of possible values: 10
Probability: 1/10 or 0.1
