ANSWER
C) Triangle
EXPLANATION
Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
We use the sine rule and cosine rule to find the missing sides and angles.
If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.

Answer:
0.141
Step-by-step explanation:
There are ₇C₁ ways to choose 1 woman from 7.
There are ₅C₃ ways to choose 3 men from 5.
There are ₁₂C₄ ways to choose 4 people from 12.
So the probability is:
₇C₁ ₅C₃ / ₁₂C₄
7 × 10 / 495
0.141
