Answer:
¼
Step-by-step explanation:
The probability of having a boy is ½ and that of a girl is ½.
Probability of boy, boy is (pb*pb) and given pb to be ½ then we can prove the point as follows
For these two children
The options are as follows
1 boy(first) and 1 girl
2 boys
2 girls
1 girl( first) and 1 boy
These are four possible options and the option for two boys is 1 out of the four.
The probability of 2 boys is ½*½=¼
Only 1,4 2,3 3,2 4,1
there are 6x6 =36 combination
so 4/36 =1/9
the answer is 1/9
Answer:
the straight line will always equal 180 degrees.

the answer for the missing degree is 20
Those are alternate interior angles and are equal. B.5x=80 x=16.
