Explanation:

total no. of cases=36

A---total favorable conditions =4

P(A)=4/36=1/9

B---total favorable cases=10

P(B)=10/36=5/18

now P(AnB)=4/36=1/9

P(AuB)=10/36=5/18

now P(A/B)=P(AnB)/P(B)=2/5

now if P(AnB)=P(A)×P(B) then A and B are independent otherwise not

so we get P(AnB) is not equal to P(A)×P(B)

so A and B are not independent
