Event A is the first event I presume?

I gave you a link for calculating probability of dependent events in your last question (how!)
This question is the same.

Use the equation and put the 2 probabilitis  into th ebalnks to get the answer

mrnood · Answer

First show your working to calculate the 
P(A)   (hint there are 36 possible outcomes from rolling 2 dice)
P(B)   (the same hint)
