: Gender of Children: Constructing Sample Space. This section included a table summarizing the gender outcomes for a couple planning to have three children.
a. Construct a similar table for a couple planning to have four children
b. Assuming that the putcomes listed in part (a) are equally likely, find the probability of getting exactly two girls and two boys.
c. Find the probability that the four children are all boys This question is from textbook
You can put this solution on YOUR website! Gender of Children: Constructing Sample Space. This section included a table summarizing the gender outcomes for a couple planning to have three children.
a. Construct a similar table for a couple planning to have four children
1st column: b : g
2nd column: put a b and a g branch on b and on g
3rd column: put a b and g banch of each of the b's and each of the g's
4th column: Do the same thing again
You should end up with 16 branches in the 4th column
-----------------------------------------
b. Assuming that the putcomes listed in part (a) are equally likely, find the probability of getting exactly two girls and two boys.
P(2g and 2b) = 4C2(1/2)^2*(1/2)^2 = 6/16 = 3/8
-----------------------------------------
c. Find the probability that the four children are all boys
P(4 boys) = 1/16
