We have a flawed dice, throws for 1 and 6 have a higher probability: P2=P3=P4=P5, P1=P6=6/5 P2. What are the probabilities? A human throws the dice twice (the second throw is independent of the first). What is the probability that we will throw the same number?

P2=5/32
P1=3/16
It's kind of sad you don't know how to do algebra.

The probability that we will throw the same number is ~0.168.

The probability will be rational, and should be expressed as such.
