I really need help!!!

Zigmanuir [339]

Answer:

$Pr = 6.67\%$

Step-by-step explanation:

Given

$n = 10$ i.e. 10 people

Required

Probability of being next to each other

First, we calculate the total possible arrangements (without any restriction)

$Total = n!$

$Total = 10!$

If the three are to be next to each other,

First, we arrange the three

$r_1 = 3!$

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)

The arrangement is:

$r_2 =8!$

So, the total arrangement, when they have to be next to one another is:

$r = r_1 * r_2$

$r = 3! * 8!$

The probability is:

$Pr = \frac{r}{n}$

$Pr = \frac{3! * 8!}{10!}$

Expand

$Pr = \frac{3*2*1 * 8!}{10*9*8!}$

$Pr = \frac{3*2*1}{10*9}$

$Pr = \frac{6}{90}$

$Pr = 0.0667$

Express as percentage

$Pr = 0.0667 * 100\%$

$Pr = 6.67\%$

NO LINKS!! Stat whether A and B are independent or dependent. Part 2

Charra [1.4K]

Answer:

Step-by-step explanation:

A). "If you do not study and fail the next test"

Two statements are combined in the given statement.

"If you don't study" and "fail the next test"

Second statement is the consequence of the first statement.

Therefore, events are dependent.

B). If you select a card from a deck and without replacing it, you select another card.

Here, selection of a card from a deck without replacing it doesn't affects the selection of another card.

Therefore, both the events are independent.
