Answer 3

Probability of randomly selecting an English book from a library

To calculate the probability of randomly selecting an English book from a library, we need to know the total number of books in the library and the number of books written in English.

According to the information provided, there are 140 books in the library, with 28 of them written in English and the rest in Russian.

To calculate the probability, we can use the following formula:

Probability = Number of English books / Total number of books

Plugging in the values, we have:

Probability = 28 / 140

Simplifying the fraction, we get:

Probability = 0.2

Therefore, the probability of randomly selecting an English book from the library is 0.2 or 20%.

Please note that the precision requested is 0.01, so we can round the probability to two decimal places.

Probability = 0.20
