Probability of correct answer+ wrong answer=1 Probability of wrong answer is 1/3 Therefore, Probability of correct answer is 1-1/3=2/3 But 2/3=p/12 Therefore p=8

P(correct answer) + P (wrong answer) = 1
    p/12                   +     1/3                      = 1
 p/12   =     1 - 1/3
p/12  = 2/3
p    = 2/3 * 12
p =  24/3
p  = 8
