Answer:
The probability of <em>X</em> = 4 is 0.21.
Step-by-step explanation:
The discrete probability distribution of the random variable <em>X</em> is:
<em> x</em>: 3 | 4 | 5 | 6
P (x): 0.17 | ___ | 0.35 | 0.27
The properties of a probability distribution are:
- 0 ≤ P (X) ≤ 1
- ∑ P (X) = 1
All the probability value are more than 0 and less than 1.
Compute the probability for <em>X</em> = 4 as follows:
Thus, the probability of <em>X</em> = 4 is 0.21.
