Suppose a cellular telephone is equally likely to make zero

Question

Question: Suppose a cellular telephone is equally likely to make zero handoffs (H₀), one handoff (H₁), or more than one handoff (H₂). Also, a caller is either on foot (F) with probability 5/12 or in a vehicle (V).

(a) Given the preceding information, find three ways to fill in the following probability table:

(b) Suppose we also learn that 1/4 of all callers are on foot making calls with no handoffs and that 1/6 of all callers are vehicle users making calls with a single handoff. Given these additional facts, find all possible ways to fill in the table of probabilities.
