What is the probability of getting a sum of 9 from two throws of a die?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → \(\displaystyle\frac{1}{9}\)
Two throws of a die give \(6\times6=36\) equally likely outcomes. Count those whose total is 9.
Totals of 9: (3, 6), (4, 5), (5, 4), (6, 3), that is, 4 outcomes
Probability \(=\displaystyle\frac{4}{36}=\frac{1}{9}\)
