Find the solution of system of equation y= x-4 y=4x+2

The probability that a college student belongs to a health club is 0.3. the probability that a college student lives off-campus is 0.4. the probability that a college student belongs to a health club and lives off-campus is 0.12. find the probability that a college student belongs to a health club or lives off-campus. tip: p(a or b) = p(a) + p(b) - p(a and b) 0.54 0.58 0.70 0.82

According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)
