Melissa rolls 2 fair dice and adds the results from each.
Work out the probability of getting a total less than 12.

Answer 1

Answer:

35/36

Step-by-step explanation:

total outcome: 6 x 6 = 36

getting 12: 1/36

getting less than 12: 1 - 1/36 = 35/36

Answer 2

Answer:

35/36

Step-by-step explanation:

The sum can be between 2 and 12.

P(sum < 12) = 1 - P(sum = 12)

Sum = 12: (6,6)

P(sum < 12) = 1 - 1/36

35/36
