Going to the movies

Assiste cada filme UMA VEZ. Logo,temos no 1º dia 4 possibilidades,no 2º dia 3 possibilidades, no 3ºdia 2 possibilidades e no 4º dia 1 possibilidade. Ou seja: 4 x 3 x 2 x 1 = 24

Max has : 4 probability in the first turn, 3 in the next turn, 2 in the next turn, and finally just 1 left. so he could watch it with 4x3x2x1 different orders = 24 orders

As Max has got 4 new movies as gifts...

so he can watch in 24 different orders....

1 \times 2 \times 3 \times 4 = 24

there are 4 movies and we have to arrange them in way that there would be no repetition and this can be done in 4! ways

4!=4x3x2x1 Multiply them all. 4!=24 Therefore,24 is the answer. Got it?

Ele Pode Ir de Diversas Maneiras sem se Importar a Ordem Assim Você Só Calcula o Número de Maneiras pelo Número de Ingressos :

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

For answer he question, we only need to do the fatorial of the number 4. 4! = 4 3 2*1 4!= 24

4 * 3 * 2 * 1 = 4! pick one random from 4 than pick one from the remaining 3 and then one from the remaining 2
