Answer:

2

Step-by-step explanation:

1/6 x 12 = 2

2/3 x 12 = 8

8 + 2 = 10

12 - 10 = 2

Answer:

2 not wearing either blue or white

Step-by-step explanation:

Find out the fraction that represents those that are wearing either blue or white. Let x be that fraction

x = 2/3 + 1/6

Change 2/3 and 1/6 to 12ths. because there are 12 students in the class.

2/3 = 2*4 / (4 *O 4) = 8/12

1/6 = 2*1/(2 * 6) = 2 / 12

x = 8/12 + 2/12

x = 10/12   Normally you would reduce this fraction because we are not using the Lowest common Denominator. In this case we just leave it.

There are 12/12 - 10/12 = 2/12 that are missing.

So 2 people are Not wearing either blue or white.

Alenkasestr [34]

Answer:

1. 3/14

2. 2/7

3. 1/7

4. 5/14

5. 11/14

6. 9/14

Step-by-step explanation:

first get the total number of pens

3 red pens + 4 blue pens + 2 black pens + 5 green pens =

14 total number of pens

1. What is the probability that the pen chosen red?

3 red pens out of a total of 14 pens = 3/14

2. What is the probability that the pen chosen is blue?

4 blue pens out of a total of 14 pens = 4/14 -> simplified -> 2/7

3. What is the probability that the pen chosen is black?

2 black pens out of a total of 14 pens = 2/14 -> simplified -> 1/7

4. What is the probability that the pen chosen is green?

5 green pens out of a total of 14 pens = 5/14

5. What is the probability that the pen chosen is NOT red?

of the 3 red pens, 4 blue pens, 2 black pens and 5 green pens

4 blue pens, 2 black pens and 5 green pens are NOT red

4 blue pens + 2 black pens + 5 green pens =

11 total number of pens that are NOT red

11 total number of pens that are NOT red out of a total of 14 pens = 11/14

6. What is the probability that the pen chosen is NOT green?

of the 3 red pens, 4 blue pens, 2 black pens and 5 green pens

the 3 red pens, 4 blue pens, 2 black pens are NOT green

3 red pens + 4 blue pens + 2 black pens =

9 total number of pens that are NOT green

9 total number of pens that are NOT green out of a total of 14 pens = 9/14
