Question

0 0.15

1 0.1
2 0.15
3 0.6
Find the mean of this probability distribution. Round your answer to one decimal place.

Answer 1

To find the mean, we add all the numbers and divide by how many there are.
0.15+0.1+0.15+0.6=1
1/4=0.25
We then round up to one decimal point resulting in an answer of 0.3
