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 1

Вероятность равна 4/20=1/5

Answer 2

Calculation of Probability

To find the probability that a yellow taxi will arrive at the customer, we need to calculate the ratio of the number of yellow taxis to the total number of available taxis.

According to the information provided, there are currently 20 taxis available: 9 black, 4 yellow, and 7 green.

Therefore, the probability of a yellow taxi arriving at the customer can be calculated as follows:

Probability = Number of Yellow Taxis / Total Number of Taxis

Probability = 4 / 20 = 0.2

So, the probability that a yellow taxi will arrive at the customer is 0.2 or 20%. Please note that the calculation assumes that all taxis have an equal chance of being selected for the customer's request.
