Answer: 
<u>Step-by-step explanation:</u>
"At least one girl" means P(1 girl) + P(2 girls) + P(3 girls) or 1 - P(all boys)
I will use the latter: 1 - P(all boys)
P(all boys) = 

Answer:
The value of the trigonometric-ratio:
Step-by-step explanation:
Given the angle X
It is clear that:
- The opposite of the angle X = 48
- The adjacent to the angle X = 14
We know that the trigonometric-ratio of Tan X is defined as
Tan X = Opposite / Adjacent
substituting Opposite = 48, and Adjacent = 14
Tan X = 48/14
Tan X = 24 / 7
Therefore, the value of the trigonometric-ratio:
Answer:
1/3
