you roll an 8 sided die and your friends rolls a 4 sided die find the probability that you and your friend roll the same umber

1/8.

Step-by-step explanation:

Assume the 8 sided die contains the numbers 1 to 8 and the 4 sided die contains the numbers 1 to 4.

There are 8 * 4 = 32 combinations of numbers possible when you throw each die once.

There are only 4 ways possible to roll the same number (1-1, 2-2, 3-3 and 4-4).

So the required probability = 4/32 = 1/8.

(1/8) x (1/4) = 1/32 which is approximately 0.03125% if you need it.
