Answer:
3/36+2/36=5/36
Step-by-step explanation:
When two dices are thrown total outcomes n(S)=36
Favorable out comes for getting 10 are (6,4)(4,6)(5,5)
Probability=3/36
Favorable outcomes for getting 11 are (6,5)(5,6)
Probability=2/36
Both are mutually exclusive events
Required probability = 3/36+2/36=5/36
