On average, how many times must a 6-sided die be rolled until a 6 turns up twice in a row?

Chance of one 6: 1/6
Chance of two 6s: (1/6)² = 1/36

Hello There!

The chance of rolling a 6 on 2 dice is 1/6 x 1/6.
1/6 x 1/6 = 1/36.
The average number of times for the first 6 would be 6
I'm not sure how to explain this part
But the average number of times for the second one would be 7.
To get the consecutive number of times, multiply them together:
6 x 7 = 42.
It would take an average of 42 times.

Hope This Helps You!
Good Luck :)
