Alright, we have six balls, numbered 1 to 6 selected one after the other With Replacement.
The sum of the numbers is 10.
So, we have to consider all possible scenario that leads to us getting 10.
Which are 5 + 5, 6 + 4, 4 + 6 (6,4 & 4,6 are different)
What is the probability that one of the balls picked was numbered 6?
we have 6 in 2 out of the 3 possible scenarios.
So, the answer is 2/3.
