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

That did not help at all, actually irrelevant. You cant simply find mean, I have tried countless times on same problem

To find the mean of a probability distribution, you need to multiply each value of x by its corresponding probability, and then sum up those products. In this case, the mean can be calculated as follows:

Mean = (0 * 0.3) + (1 * 0.3) + (2 * 0.2) + (3 * 0.2)

Mean = 0 + 0.3 + 0.4 + 0.6

Mean = 1.3

Therefore, the mean of this probability distribution is 1.3, rounded to one decimal place.

Mean = sum of scores divided by number of scores.
