Problem Analysis

We are given that a taxi company currently has 20 cars available: 2 black, 2 yellow, and 16 green. One of the cars is dispatched to a customer, and we need to find the probability that a black taxi will arrive.

Solution

To find the probability, we need to determine the number of favorable outcomes (black taxis) and the total number of possible outcomes (all taxis).

The number of favorable outcomes is the number of black taxis, which is 2.

The total number of possible outcomes is the total number of taxis, which is 20.

Therefore, the probability of a black taxi arriving is given by:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 2 / 20

Simplifying the fraction, we get:

Probability = 1 / 10

So, the probability that a black taxi will arrive is 1/10.
