You have a bag of 12 marbles. Four are blue, 6 are green, 2 are red, and the others are yellow. What is the probability of drawi
8090 [49]

Answer:

Probability = \frac{1}{11}

Step-by-step explanation:

Given

Blue = 4

Green = 6

Red = 2

Total = 12

Required

Determine the probability of drawing red and green without replacement

This is calculated as follows:

Probability = P(Red\ and\ Green)

Probability = P(Red)\ and\ P(Green)

Probability = \frac{n(Red)}{Total} * \frac{n(Green)}{Total - 1}

We used Total - 1 because it's a probability without replacement:

Probability = \frac{2}{12} * \frac{6}{12- 1}

Probability = \frac{2}{12} * \frac{6}{11}

Probability = \frac{1}{6} * \frac{6}{11}

Probability = \frac{1}{11}

<em>Hence, the required probability is 1/11</em>

You are rolling two dice. When the two numbers (1-6) come up, you multiply the numbers
Tasya [4]

Answer:

1/4 probability of getting a product that isn't divisible by 2.

Step-by-step explanation:

These are all the possible outcomes

1 x 1 = 1    2 x 1 = 2    3 x 1 = 3     4 x 1 = 4     5 x 1 = 5      6 x 1 = 6

1 x 2 = 2   2 x 2 = 4   3 x 2 = 6     4 x 2 = 8    5 x 2 = 10    6 x 2 = 12

1 x 3 = 3  2 x 3 = 6    3 x 3 = 9     4 x 3 = 12   5 x 3 = 15   6 x 3 = 18

1 x 4 = 4   2 x 4 = 8   3 x 4 = 12     4 x 4 = 16   5 x 4 = 20  6 x 4 = 24

1 x 5 = 5   2 x 5 = 10  3 x 5 = 15   4 x 5 = 20  5 x 5 = 25  6 x 5 = 30

1 x 6 =  6   2 x 6 = 12  3 x 6 = 18   4 x 6 = 24   5 x 6 = 30  6 x 6 = 36

All of the outcomes that aren't divisible by 2 are in bold

There are 9 out of 36 possible outcomes that aren't divisible by 2

9/36 = 1/4

Which statement is true about the end behavior of the
mihalych1998 [28]

As the x-values go to positive infinity, the function's values go to positive infinity, Option D is the correct answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement that relates an independent variable with a dependent variable .

The graph is given in the question and the statement that correctly matches to the behaviour shown is asked .

When X values is increasing , the y value is increasing and

when the x value is decreasing the y value is also decreasing

Therefore the correct Option that can be chosen from the given is Option D

As the x-values go to positive infinity, the function's values go to positive infinity.

PLZZZZ HELLPP  50 POINTS TO WHO CAN ANSWER CORRECTLY
finlep [7]
For this case we are going to assume that Nina wrote:
 3/4 (1440) + 295.25 + (-33.50).
 The expression is correct since we have:
 ticket sales were three-fourths as much as yesterday. That means
 3/4 (1440)
 food sales were down by $ 33.50, that means:
 295.25 + (-33.50)
 Therefore, today's sales were:
 3/4 (1440) + 295.25 + (-33.50).

 Nina's expression is correct
