8.

А. Сколько различных пятизначных чисел можно составить из цифр 1, 2, 3, 4, 5 при условии, что ни одна цифра в числе не повторяется?

Б. В соревнованиях участвовали 4 команды. Сколько вариантов распределения мест между ними возможно?

Решение 2 (rus). №8 (с. 146)

А. Эта задача относится к комбинаторике, а именно к перестановкам без повторений. У нас есть 5 различных цифр (1, 2, 3, 4, 5), из которых нужно составить пятизначные числа так, чтобы цифры не повторялись. Это означает, что нам нужно найти количество всех возможных перестановок из 5 элементов.

Количество перестановок из n элементов вычисляется по формуле $P_n = n!$, где $n!$ (n-факториал) – это произведение всех натуральных чисел от 1 до n.

В нашем случае n = 5, так как у нас 5 цифр.

Вычисляем количество возможных чисел:

$P_5 = 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120$

Таким образом, можно составить 120 различных пятизначных чисел.

Ответ: 120.

Б. Эта задача также является задачей на перестановки. Есть 4 команды, и нужно распределить между ними 4 места (1-е, 2-е, 3-е, 4-е). Каждая команда может занять только одно место, и каждое место может быть занято только одной командой. Следовательно, нам нужно найти число всех возможных способов расставить 4 команды по 4 местам.

Это количество перестановок из 4 элементов, которое вычисляется по формуле $P_n = n!$.

В данном случае n = 4.

Вычисляем количество вариантов распределения мест:

$P_4 = 4! = 4 \times 3 \times 2 \times 1 = 24$

Следовательно, существует 24 варианта распределения мест между командами.

Ответ: 24.
