In a class 23 of students, 10 play an instrument and 15 play a sport. There are 7 students who play an instrument and also play a sport. What is the probability that a student does not play a sport given that they play an instrument?

The probability that a student does not play a sport given but they play an instrument is 3/23

Step-by-step explanation:

Total students in a class = 23

Students who play sports = 15

Students who play instruments = 10

Students who play both = 7

Probability that a student play sports = 15/23

Probability that a student play instruments = 10/23

Probability that a student play both = 7/23

Probability that a student does not play a sport given but they play an instrument = probability that a student play instruments - Probability that a student play both

= (10-7)/23

= 3/23

The probability that a student does not play a sport given but they play an instrument is 3/23

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
