Answer:

1.333 is more close to 1.5 than 1.25 .

Step-by-step explanation:

We are given:

You have a 4 in. X 6in. family picture that you want to resize. You can choose from a 16 in. X 20 in. or an 18 in. X 24 in. Which size will keep more of the original picture.

First divide 6 by 4: we get,

6/4 = 1.5 inches

This is the ratio to achieve.

Now divide 20 by 16

20/16 = 10/8

10/8 = 5/4

5/4 = 1.25 inches

Now divide 24 by 18

24/18 = 12/9

12/9 = 4/3

4/3 = 1.333 inches

1.333 is more close to 1.5 than 1.25 .

Twenty identical looking packets of white power are such that 15 contain cocaine and 5 do not. Four packets were randomly select

xxMikexx [17]

Answer:

The probability of selecting randomly 6 packets such that the first 4 contain cocaine and 2 not is 0.3522.

Step-by-step explanation:

Probabilities of selecting 4 packets with the ilegal substance:

$(\frac{15}{4})\\$ = $\frac{15!}{4!(15-4)!}$

Combinassions possible= 1365

Probabilities of selecting 2 packets with white powder:

$(\frac{5}{2})$ = $\frac{5!}{2!(5-2)!}$

Combinations possible= 10

Probabilities of selecting 6 packets from the totality of them:

$(\frac{20}{6})$ = $\frac{20!}{6!(20-6)!}$

Combinations possible= 38760

The probability of picking 4 with the substance and 2 with only white powder is:

$\frac{(15ncr4)(5ncr2)}{(20ncr6)}$ = 0.3522

I hope this answer helps you.
