Question

Students in the high school choir sing one of four voice parts. tenors 2 sopranos 9 altos 20 basses 14 What is the probability that a randomly selected singer will be a soprano? Write your answer as a fraction or whole number.

Answer 1

9/53. add up the number of students (denominator) and out of those students which ones are the soprano (numerator)

Answer 2

Okay, here are the steps to solve this problem:

* There are 10 tenors, 9 sopranos, 20 altos, and 14 basses in the choir

* In total there are 10 + 9 + 20 + 14 = 53 singers

* There are 9 sopranos out of the 53 total singers

* To find the probability of a randomly selected singer being a soprano:

* Probability = (Number of desired outcomes) / (Total possible outcomes)

* So Probability = 9/53

Therefore, the probability that a randomly selected singer will be a soprano is 9/53
