Question

What is the probability of spinning these two spinners and having each one land

on a 3? Write the probability as a decimal.

Answer 1

The probabilities are 0.4 and 0.6 respectively.

Explanation:

We are given two spinning wheels with numbers on it and we have to find the probability of getting 3.

In the first wheel, there are 5 slots and the numbers are 3, 3, 2, 5 and 4.

So the probability of getting 3 =
`(number of 3's)/(total number of slots)`

=
`(2)/(5)`

= 0.4

In the second spinner there are three 3's and total of 5 slots.

So probability of getting 3 =
`(number of 3's)/(total number of slots)`

=
`(3)/(5)`

= 0.6

Hence the probabilities are 0.4 and 0.6 respectively.
