The excercise is:
The problem says:
We have a dice
It's numbered from 1 to 6
We roll it two times and each time we record the number we get
The first roll/number we record is "a"
and the second is "b"
The question says: Calculate the probability of each one of these:
A) "The two numbers a and b apply the equation: b = 2a + 1"
B) "a and b apply: |a - b | < 1"
C) "a and b apply: |a - b| > 5"
Here is how I solved it:
P(A) = 2 / 36
P(B) = 1
P(C) = 0
Is it correct? Please tell me with justification.
