Melissa rolls 2 fair dice. The probability of getting a total of 12 is

Solution:

Given, Melissa rolls 2 fair dice and adds the results from each.  

We have to work out the probability of getting a total of 12

The probability of an event is given as follows:

Now, total outcomes = 6 for 1st die 6 for 2nd die = 6 6 = 36.

Now, favourable outcomes = 1 [ since, we have to get a sum of 12, and only one case exists i.e. 6 + 6]

Hence the probability of getting a total of 12 is

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
