Problem If you roll a fair six-sided die and a fair four-sided die, what is the probability that neither die shows a 1?

Question

please help me with this difficult math problem

Answer 1

Chance a 1 will NOT appear on the six sided die = 5/6

Chance a 1 will NOT appear on the four sided die = 3/4

 

Cahnce of NOT getting a 1 on either die :

 

(5/6)*(3/4) = 15/24

 

15/24 = 5/8

 

5/8 = 0.625
