Answer:

1/4

Step-by-step explanation:

It would be 1/4 because for the first child, the probability of it being a boy is 1/2, and for the second one, it would have 1/2 as well. There are 4 ways the first two children could have been:

1. boy boy - it is 1/4 of the options.

2. boy girl

3. girl boy

4. girl girl

Another way to solve it is by multiplying 1/2 by 1/2.

Need to find what x and y equals
dexar [7]

The two angles with x in them are the same. Set them equal to each other and solve for x:

4x-5 = 3x + 11

Add 5 to both sides:

4x = 3x +16

Subtract 3x from both sides:

x = 16

Now solve for the angle next to y:

4x - 5 = 4(16) -5 = 64 -5 = 59

Y + 59 make a straight line and equals 180, so subtract 59 from 180 to get y:

y = 180 - 59 = 121

Answers:

X = 16, y = 121
