1+2=21, 2+3=36, 3+4=43, 4+5=52.
Assuming the distribution is continuous, you have
If instead the distribution is discrete, the value will depend on how the interval of number between 1 and 29 are chosen - are they integers? evenly spaced rationals? etc
9/50 is the answer I think!
I converted 9/10 to decimal to make it easier for me to solve and got 0.9
I divided 0.9 by 5 and got 0.18
I converted 0.18 to fraction and got 9/50
