Question

an athletic has 246 members of these 164 lift weights and 208 perform cardiovascular exercises regularly all members do at least one of these activities. How many do both?

Answer 1

Any body know this

Answer 2

let A=lift weights,B=perform cardiovascular exercises
from the data ,n(A)=164,n(B)=208,n(AUB)=246,to find n(A and B)
the formula is n(A and B)=n(A)+n(B)-n(AUB)
so n(A and B)=164+208-246
can u solve further??
