Question

В коллекции 150 монет, из них 22 монеты XVI века, 15 монет XVII века, 23 монеты XVIII, ЕСТЬ ЕЩЕ МОНЕТЫ XIX и XX веков. Найдите вероятность того, что при случайном выборе одной монеты будет выбрана монета XIX или XX веков .

Answer 1

22 + 15 + 23 =60
150-60=90
90/150=0,6

Answer 2

Calculation of Probability

To find the probability of randomly selecting a coin from the collection that is from the XIX or XX century, we need to calculate the ratio of the number of coins from the XIX and XX centuries to the total number of coins in the collection.

Given the information provided, we know that the collection consists of 150 coins, with the following distribution:

- 22 coins from the XVI century - 15 coins from the XVII century - 23 coins from the XVIII century - The remaining coins are from the XIX and XX centuries.

To calculate the probability, we need to determine the number of coins from the XIX and XX centuries. Since the exact number is not specified, we can only conclude that there are some coins from these two centuries.

Therefore, we cannot provide an exact probability without additional information about the number of coins from the XIX and XX centuries in the collection.

If you have any additional information or if there is anything else I can assist you with, please let me know!
