Question

Spinner has

10
equally sized sections,
4
of which are gray and
6
of which are blue. The spinner is spun twice. What is the probability that the first spin lands on blue and the second spin lands on gray ?
Write your answer as a fraction in simplest form.

Answer 1

(6/10) × (4/10) = (2.4/10)

Answer 2

First spin lands on blue, we notice that 6 sections out of 10 are blue. This is 60%.

Second spin lands on gray, we notice that there are 4 sections out of 10. This is a 40% chance.

In order to find the probability of both spins together, we need to do the math as follows.

What's 60% of 40%. Or .6 X .4. Or 6/10 X 4/10. It's all the same thing.

If you did the math in either way, you get 24%.

Hope this helps!
