Question

. В фирме такси в данный момент свободно 20 машин: 9 черных, 4 желтых и 7 зеленых. По вызову выехала одна из машин, случайно оказавшаяся ближе всего к заказчику. Найдите вероятность того, что к нему приедет желтое такси.

Answer 2

Calculating the Probability of a Yellow Taxi Arrival

To calculate the probability of a yellow taxi arriving, we can use the information provided about the total number of available taxis and the specific number of yellow taxis.

Given: - Total number of available taxis = 20 - Number of yellow taxis = 4

Formula for Probability Calculation

The probability (P) of an event is calculated using the formula: \[ P = \frac{m}{n} \] Where: - \( m \) = Number of favorable outcomes (in this case, the number of yellow taxis) - \( n \) = Total number of possible outcomes (in this case, the total number of available taxis)

Applying the Formula

Using the given values: - \( m = 4 \) (number of yellow taxis) - \( n = 20 \) (total number of available taxis)

\[ P = \frac{4}{20} = 0.2 \]

Result

The probability that a yellow taxi will arrive is 0.2 or 20%.

This calculation assumes that all taxis have an equal chance of being selected for a call.

Remember, the actual probability may vary based on specific circumstances and factors not considered in this calculation.
