Answer:

1 in 132.

Explanation:

In this case, the selection cannot be repeated, so every time we select someone, the other people's chance of being selected increases.

There are 6 couples, which means there are 12 people. We have a 1 in 12 chance of choosing a certain person, the person we pick is named Dan. Then there are 11 people, we now have a 1 in 11 chance of picking Dan's partner. The probability increased because Dan cannot be picked again. 12 x 11 is 132.

Give your opinion WHY it is BETTER to read PAPER books RATHER than online books.
Vaselesa [24]

Answer:

because you'll absorb more information. how? when reading a paperback book, you can annotate, which you cannot do with an online book. and for me personally, there's just something so magical about the smell of the glue and paper and the feeling and sound the pages make when you flip them.

good luck :)

i hope this helps

have a nice day!

When Jonas realized he could see color, it contrasted from the normal grey scale he and his community usually experience.
His new life contradicted his past life before his job assignment because he was told he could never lie but not with his job, he has the right to.
He also realized what the government was doing immorally and that contradicted his old view of his government, which was that they are faultless.
