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 x
p(x)

0
0.125
1
0.375
2
0.375
3
0.125
choose the correct answer below.

Given:
Number of girls x      P(x)
0                             0.125
1                             0.375
2                             0.375
3                             0.125

What is the random variable?
The random variable is x. x represents the number of girls in three births

What are its possible values?
The possible values of x are 0,1,2, and 3.

Are its values numerical?
Yes, the values are numerical because 0,1,2, and 3 are numbers. 

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
