The formula is a permutation in which n represents the sample points in the set, while r represents the number of sample points in each permutation.
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.

Answer:
A.4
Step-by-step explanation:
Because 4/12 is simplified to 1/3 and 2/4 would be simplified to 1/2. 1/2 > 1/4
Answer:
D. 5/4
Step-by-step explanation:
A. 5.4 can't be 'cause the shade did not reach 5 on number line.
B. 5 - 4 = 1 can'e be 'cause it pass 1.
C. 4 / 5 = 0.8 can't be 'cause its less than the shade.
D. 5 / 4 = 1.25 correct
