s and develops the probability distribution below for a randomly selected student. What is the mean of the probability distribution?
2 answers:
Answer:
Mean = 1.5
Step-by-step explanation:
We are given a table of probability distribution of students the numbers of hours studied.
We need to find the mean of the probability distribution.
Formula of mean = sum of product of probability and random distribution value.
Now we will calculate the mean
Thus, Mean of the given table is 1.5

divide 2.2 by 6.8 then z would equal 3.09
Answer:
obviously it's 3. from the answer of 3 is to 5
Answer:
Probably like a 80 or high C.
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5
It will take 5 hours.
