Answer 2

P(X < 4) for the given probability distribution is P(X < 4) = 0.25.

P(X < 4) for the given probability distribution, you need to sum the probabilities associated with the values of X that are less than 4.

The given vertices, you can see that the probability is 0 for X = 0 and X = 11, and it is 0.15 for X = 6 and 0.10 for X = 10. P(X < 4) is the sum of probabilities for X = 0, X = 6, and X = 10, the calculation is as follows:

P(X < 4) = P(X = 0) + P(X = 6) + P(X = 10)

P(X < 4) = 0 + 0.15 + 0.10

P(X < 4) = 0.25

Therefore, P(X < 4) = 0.25.
