A bag contains 7 red marbles, 3 blue marbles and 5 green marbles. If three marbles

worty [1.4K]

Answer:

3.7%

Step-by-step explanation:

We know that from this situation, the probability of drawing a single green marble is 1/3. However, to find the probability of drawing 3 green marbles, we will need to do:

$P= \frac{1}{3}* \frac{1}{3}*\frac{1}{3}$

We get a probability of:

$P= \frac{1}{27}$

This converts to a percentage of:

$\frac{1}{27}= 0.037 \\ 0.037*100= 3.7%$

We get a percentage of 3.7%

Slove by using elimination <br> 3x+7y=27 <br> -3x+y=21

tankabanditka [31]

Answer:

x = -5

y = 6

Step-by-step explanation:

3x + 7y = 27 --------------(I)

-3x + y = 21 -----------(II)

Add equation (I) & (II) and so x will be eliminated and we can find the value of y.

(I) 3x + 7y = 27

(II) <u> -3x + y = 21 </u> {add}

8y = 48

y = 48/8

y = 6

Plugin y = 6 in equation (I)

3x +7*6 = 27

3x + 42 = 27

3x = 27 - 42

3x = -15

x = -15/3

x = -5
