посетитель может войти через один из 4 входов:A,B,C,D, тогда вариантов выйти у него остается 3(т.к. один он уже использовал при входе). Таким образом количество способов равно = 4*3=12

Answer 2

Possible Ways to Enter and Exit the Stadium

A stadium with four entrances (A, B, C, D) offers several possibilities for visitors to enter through one entrance and exit through another. Let's explore the different ways this can be done.

To determine the number of possible ways, we need to consider the number of choices for the entrance and the number of choices for the exit. Since there are four entrances and four exits, each visitor has four options for both entering and exiting the stadium.

Therefore, the total number of possible ways for a visitor to enter through one entrance and exit through another is calculated by multiplying the number of choices for the entrance (4) by the number of choices for the exit (4). This gives us a total of 16 possible ways for a visitor to enter through one entrance and exit through another.
