Why is the table not a probability distribution table?

Mathematics
1 answer:
jeyben [28]2 years ago
8 0

Using <u>probability distribution concepts</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

  • In a probability distribution, the <u>sum of all probabilities has to be equals to 1</u>.

In this problem, the probabilities are: 0.25, 0.45, 0, 0.35.

Their sum is:

0.25 + 0.45 + 0 + 0.35 = 1.05

Since the <u>sum is not 1</u>, the correct option is:

  • C. the sum of the probabilities is not 1.00

A die is rolled 20 times. given that three of the rolls came up 1, five came up 2, four came up 3, two came up 4, three came up
Serjik [45]

Solution:

Number of times a die is rolled = 20

1 - 3=A

2 - 5=B

3 - 4=C

4 - 2=D

5 - 3=E

6 -  3=F

Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times

            = Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes

= 6! × [ 3! × 5! × 4!×2!×3!×3!]

= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]

= 895795200  Ways

Solve for c.
tensa zangetsu [6.8K]
-58c=20     isolate variable with equal treatment using opposite operation
opposite of -58 x c is division, so divide both sides by -58
-58c/-58  = 20/-58 
-58 over -58 = 1 so
1c = 20/-58
c = -0.3448275    Round to nearest hundredth = -0.34
