Answer:
3/7.
Step-by-step explanation:
The total number of ways to pick 4 out of 8 = 8C4
= 8!/ 4!4!
= 70 ways.
The number of ways when 2 are women = 5C2 * 3
= 10 * 3
= 30.
So the required probability = 30/70
= 3/7.

Answer: The ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
Step-by-step explanation:
Given : Number of students who play the clarinet= 12
Number of students who play the viola=16
We know that ratio of A to B is represented by A:B.
Since, the number '12' is representing " students who play the clarinet" and number '16' is representing " students who play the viola"
So , the ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
