oey is conducting an experiment in which he will roll a six-sided die, numbered 1 to 6, record its result, and then roll a ten-sided die, numbered 1 to 10.

What is the probability that the result of the rolls is two threes?

Okay well what are the odds of both? we have a 6 sided die...and we want a 3....so that is a 1/6 chance

then we have a 10 sides die....which is a 1/10 chance....now just add the 2 probabilities

1/6 + 1/10

Least common denominator is 60 so

10/60 + 6/60 

adding brings this to 16/60

simplifying brings it to 4/15 :) hope that helped
