Answer:
20) the answer is -43
21) the answer is 25
22)the answer is -5
Step-by-step explanation:
20)
n=-7
p=-6
we have:
21) mp-(p-(m-n))
m= -1 n=-6 p=-10
-1*-10-(-10-(-1-(-6)))
10-(-10-(5))
10-(-15)
10+15=25
22)
m=1 n=5
1-
1- 2/2 -5
1-1-5 =-5

Given:
The faces on a number cube are labeled 1,2,2,3,4, and 5.
The number cube is rolled 114 times.
To find:
How many times would you expect the number 2 to appear?
Solution:
We have,
Total outcomes = 1,2,2,3,4, and 5.
Number of total outcomes = 6
Favorable outcomes = 2 and 2
Number of favorable outcomes = 2
The probability of getting 2 is:
Now, the expected number of times when 2 to appear is:
Therefore, the expected number of times is 38.
