A pair of dice is rolled. What is the probability that the sum is 11?

1/18

Step-by-step explanation:

Number of possible outcomes:

Number of favorable outcomes:

or

Total of 2 outcomes giving 11 as a sum of two dice.

Probability of getting the sum of 11 is:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
