First,we would list out the possibilities to find the probability:
Let G represent girl and B represent boy,here are the possibilities:
1)GGGGGG
2)GBBBBB
3)GGBBBB
4)GGGBBB
5)GGGGBB
6)GGGGGB
7)BBBBBB
Since there are 7 probabilities,the probability is 1/7.
Hope it helps!

Answer:
30.25π square inches
Step-by-step explanation:
You can use the formula for area in terms of circumference:
A = C²/(4π)
A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches
_____
You may be expected to find the radius first:
C = 2πr ⇒ r = C/(2π) = 11π/(2π) = 5.5 . . . inches
Then use the area formula:
A = πr² = π(5.5 in)² = 30.25π in²
Answer:
Step-by-step explanation:
ahh 30° is the mystery angle . sooo
180-30 = 150 that angle BOA
then the other two angle are each 15°
so then BAX is 90-15=75°
