What probability value would be needed to complete the following probability distribution properly

Question

X

P(x)

6

0.16

4

0.29

3

0.24

1

0

0.09

Answer 1

X P(x)

6 0.16

4 0.29

3 0.24

1

0 0.09

total probability must sum to 1, missing probability for x=1 will be found by finding the sum of the remaining probabilities and subtracting from 1. That sum is 0.16 + 0.29 + 0.24 + 0.09 = 0.88, so P(x) for x= 1 is 1 - 0.88 = 0.12.
