0	0.3
1	0.1
2	0.25
3	0.35

Find the mean of this probability distribution. Round your answer to one decimal place.

Answer 1

Hi Sela,

To find the mean of the distribution, we multiply each x by P(x). Then we add all of those results together:

0 * 0.3 + 1 * 0.1 + 2 * 0.25 + 3 * 0.35 = 1.65 or 1.7.

Please let me know if I can be more helpful, thanks!
