Question

Can someone please teach me how to solve this question step-by-step?​

Answer 1

`(1)/(12)`

Explanation:

1) Construct a probability tree (check the attachment).

1.1) Change the given items/values into fractions. In this case, there are 3 entrees, each with a probability of
`(1)/(3)` because the probability of selecting a hamburger (an example that could be applied to other options too) is 1 out of the 3 options. Likewise is the case with sides and drinks; the probability of selecting fries (or vegetable) out of the two options is
`(1)/(2)`, and the probability of selecting milk (or juice) out of the two options is
`(1)/(2)`.
