Answer 2

I know there are 4 possible outcomes:6+3, 5+4, 4+5, 3+6, so wouldn't it be 1/4?

Answer 3

possible

Answer 4

or 4/12

Answer 5

because there are 4 outcomes and 12 numbers all together on the dice

Answer 6

Answer 7

Here the total number of points in event space is 6^2=36 and 9=3+6=6+3 =5+4=4+5 Hence only 4 points corresponds to the required solution required probability is 4/36=1/9

Answer 8

Okie dokie. If you don't understand something below then just tell me! :D

Since you have two dice, and there is 4 outcomes(6+3, 5+4, 4+5, and 3+6), and 36 possible outcomes, so we have \(\sf \large \color{magenta}{\frac{4}{36}}\) and if you simplify that you get \(\sf \large \color{magenta}{\frac{1}{9}}\)
