Answer:
I'm pretty sure your answer is going to be 12 3/20
Step-by-step explanation:
The mean of the discrete probability distribution is of 1.28.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Then, considering the given distribution, the mean is given by:
E(X) = 0(0.13) + 1(0.61) + 2(0.15) + 3(0.07) + 4(0.04) = 1.28.

5^3=125; 2.5^2=6.25. So the answer to your first question is 125, and the second one is 6.25
It would be 256 because you would do 4 to the power of 4
I believe it would be 4 1/10 ,4.104, 104/25, 4.74
