Answer:

A) 32 students

B) 50%

C) He is incorrect because more males like soccer.

Step-by-step explanation: Given that the

Total number of students = 250

Total number of male = 139

Total number female =

250 - 139 = 111

Also, it is given that 36 of the 72 that like football are male

Female = 72 - 36 = 36

Total number of female = S + B + F + b

Where B = baseball

111 = 25 + B + 36 + 18

111 = 79 + B

B = 111 - 79

B = 32 students

Part B: What percentage of females like football?

%female=female/total students×100

= 36/72 × 100

= 1/2 × 100

= 50%

Part C: Joe says that the percentage of males who like soccer is the same percentage of females who like soccer. Is he correct? Explain.

The total number for baseball is

26 + 32 = 58 students

Total number of students for soccer will be

Total students = S + B + F + b

250 = S + 58 + 72 + 63

250 = S + 193

S = 250 - 193

S = 57 students

Number of Male students who like soccer = 57 - 25 = 32

Percentage of males who like soccer = male/total students × 100

= 32/57 × 100

= 56%

Percentage of males who like soccer = male/total students × 100

= 25/57 × 100

= 44%

Therefore, he is incorrect because more males like soccer.
