There were 39 freshmen at a certain school, out of those freshmen,

15 played basketball,

17 played volleyball,

16 played soccer,

5 played basketball and volleyball,

7 played basketball and soccer,

5 played volleyball and soccer,

and 4 played volleyball, basketball, and soccer.

How many played one or more of the three sports?

Step-by-step explanation:

the number of freshmen that played basketball and volleyball only is

5 - 4 = 1

the number of freshmen that played basketball and soccer only is

7 - 4 = 3

the number of freshmen that played volleyball and soccer only is

5 - 4 = 1

the number of freshmen that played volleyball only is

17 - (1 + 4 + 1) = 11

the number of freshmen that played basketball only is

15 - (1 + 4 + 3) = 7

the number of freshmen that played Soccer only is

16 - (3 + 4 + 1) = 8

Therefore, the number of freshmen that played one or more of the sports would be

7 + 11 + 8 + 1 + 3 + 1 + 4 = 35

i think its 30
