Hint: There are 5 ways a single die can come up not a 3.

Question

If 2 six-sided dice are tossed, in how many ways can at least one of the dice come up a 3?

 

 

Answer 1

Calculate the probability of both dice NOT being a three.  This would be 5/6 x 5/6 = 25/36.

 

To figure out the possibility of there being at least one 3, you would subtract 25/36 from 1.

 

Can you take it from here?
