The answer will be three (D)
Thsi can be calculated bet using
P(AUB)=P(A)+P(B)-P(A intersection B)
which will give the answer as 3

D) 3
the total people are 25
the people play hockey is 15
the people play foot ball is 17
both are 10 people
that means the people play only hockey is 15-10=5
and football is 17-10=7
sum all the individuals and combined players gives 22
that means the remaining 3 will not play either of the games
