I have a special 6-sided dice such that

The probability of rolling a 2 is twice the probability of rolling a 1,
the probability of rolling a 3 is thrice the probability of rolling a 1,
the probability of rolling a 4 is quadruple the probability of rolling a 1,
the probability of rolling a 5 is quintuple the probability of rolling a 1, and
the probability of rolling a 6 is hextuple the probability of rolling a 1.

What is the probability of rolling an even number?

Hey there, Guest!

 

1x + 2x + 3x + 4x + 5x + 6x = 1

Therefore 21x equals 1.

 

x = \(\frac{1}{21}\)

 

Hope this helped! :)
