Answer:
P(X=0) = 0.25
P(X=1) = 0.50
P(X=2) = 0.25
Step-by-step explanation:
The possible outcomes of this event are: BB, BG, GB and GG.
There is one out of four events (GG) in which there are two girls (X=2).
There is one out of four events (BB) in which there are no girls(X=0).
There are two out of four events (GB and BG)) in which there is one girl (X=1).
Therefore, the probability distribution of X is:
P(X=0) = 1/4 = 0.25
P(X=1) = 2/4 = 0.50
P(X=2) = 1/4 = 0.25

Step-by-step explanation:
Answer:
7 females, 24 males
Step-by-step explanation:
I solved it by using this equation:
2x + 17 = 31
then, i subtracted 17 on both sides:
2x=14
then divide by 2 on both sides:
x=7
then I added 7 to 17 to find the number of males:
7+17= 24
Answer:
6
Step-by-step explanation:
find a common factor
6*8=48
8*6=48
if there are 2 rows then each row will have 78 members
