Two dice are tossed. What is the probability of getting a sum of at least 4? (Enter your probability as a fraction.)
The total number of possible outcomes when two dice are tossed is 36 (6 possibilities for each dice).
Now let's count the number of outcomes where the sum is at least 4:
- 1+3, 2+2, 3+1
- 1+4, 2+3, 3+2, 4+1
- 1+5, 2+4, 3+3, 4+2, 5+1
- 1+6, 2+5, 3+4, 4+3, 5+2, 6+1
- 2+6, 3+5, 4+4, 5+3, 6+2
- 3+6, 4+5, 5+4, 6+3
- 4+6, 5+5, 6+4
- 5+6, 6+5
- 6+6
There are a total of 30 outcomes where the sum is at least 4.
So, the probability of getting a sum of at least 4 is 30/36 = 5/6.
Therefore, the probability is 5/6.
