Question

You roll a pair of dice. What is the approximate probability that the dice shows a sum of 10 or the same number on each die?

Answer 1

probability that the dices show a sum of 10:
4,6 - 5,5 - 5,5 - 6,4 >> four outcomes



probability that the same number appears on each dice:
1,1
2,2
3,3
4,4
5,5
6,6
>>>>>>>> 6 outcomes

and all outcomes are 36 results

so our probability will be: (4+6) / 36 = 10 / 36 = 5/18 =0.2778 = 27.78%




hope that helps
