Question

The table to the right lists probabilities for the corresponding numbers of girls in three births. What is the random​ variable, what are its possible​ values, and are its values​ numerical?

Number_of_girls P(x)
0                         0.125
1                         0.375
2                         0.375
3                         0.125
 
choose the correct answer below.
 
A.
The random variable is​ P(x), which is the probability of a number of girls in three births. The possible values of​ P(x) are 0.125 and 0.375. The values of the random value​ P(x) are not numerical.
 
B.
The random variable is​ x, which is the number of girls in three births. The possible values of x are​ 0, 1,​ 2, and 3. The values of the random value x are numerical.
 
C.
The random variable is​ x, which is the number of girls in three births. The possible values of x are​ 0, 1,​ 2, and 3. The values of the random value x are not numerical.
 
D.
The random variable is​ P(x), which is the probability of a number of girls in three births. The possible values of​ P(x) are 0.125 and 0.375. The values of the random value​ P(x) are numerical.
