Determine the required value of the missing probability to make the distribution a discrete probability distribution. x P(x) 3 0.170.17 4 ? 5 0.350.35 6 0.270.27 P(4) = nothing (Type an integer or a decimal.)

The probability of X = 4 is 0.21.

Step-by-step explanation:

The discrete probability distribution of the random variable X is:

   x:   3   |  4     |   5    |   6

P (x): 0.17 | ___ | 0.35 | 0.27

The properties of a probability distribution are:

All the probability value are more than 0 and less than 1.

Compute the probability for X = 4 as follows:

Thus, the probability of X = 4 is 0.21.
