A survey of 60 people was done to see which ice cream flavor they preferred, vanilla, chocolate, or strawberry. The results are as follows: 5 liked all three flavors
9 people liked chocolate and strawberry, 11 people liked vanilla and strawberry, 13 people liked vanilla and chocolate
29 people liked chocolate, 28 people liked vanilla, 28 people liked strawberry
What is the probability that a person chosen at random prefers neither of the 3 flavours?

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

answer is because 4×10=40

and 98×4= is 392

40,392

step-by-step explanation:

you have to add all the sides together

the correct answer is the last option
