two dice are rolled in succession. determine the probability that their sum is 10 or more,given that the first die is a 5

MrRa [10]

If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.

Assuming it is a six sided die, the two values that would make this true are 5 and 6.

2 values/6 possible would be a probability of 2/6, which simplifies to 1/3

Final answer: 1/3
