in a class of students, the following data table summarizes how many students play an instrument or a sport. what is the probability that a student who plays a sport also plays an instrument?\n| | plays an instrument | does not play an instrument |\n|--|--|--| \n| plays a sport | 9 | 3 |\n| does not play a sport | 10 | 7 |
Answer
Answer:
$\frac{3}{4}$
Explanation:
Step1: Find number of students who play a sport
$9 + 3=12$
Step2: Find number of students who play a sport and an instrument
$9$
Step3: Calculate the probability
$P=\frac{9}{12}=\frac{3}{4}$
