Formlua

As given

In a school, 42% of the students liked to play football and 24% liked to play tennis.

As the percentage is always 100% .

Percentage of students choose swimming = ( 100 - 42 - 24) %

                                                                       = (100 - 66) %

                                                                       = 34 %

The rest of the students choose swimming If 170 students choose swimming .

Part value = 170

Percentage = 34 %

Putting all the values in the formula

Total value = 500

As the percentage for students liked to play football = 42%

Putting in the formula

Part value = 210

Thus

Students liked to play football = 210

Therefore the students liked to play football are 210 .

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
