p(2)= 2(13-P)                  

p(2)= 2(13-2)                  

p(2)=2(11)                        

p(2)= 22

p(3)= 2(13-p)

p(3)= 2(13-3)

p(3)= 2(10)

p(3)= 20

p(4)= 2(13-p)

p(4)= 2(13-4)

p(4)= 2(9)

p(4)= 18

v(4)w(2)= 3v+w

v(4)w(2)= 3(4) + 2

v(4)w(2)= 12+2

v(4)w(2)= 14

v(6)w(3)= 3v+w

v(6)w(3)= 3(6)+3

v(6)w(3)= 18+3

v(6)w(3)= 21

v(8)w(4)= 3v+w

v(8)w(4)= 3(8)+4

v(8)w(4)= 24+4

v(8)w(4)= 28

the answer will be

probability for j is 1/4

while

a is 1/6
