An envelope contains small strips of paper of equal size and shape. Four of the strips have the number 4 written on them, five of the strips have the number 5 written on them, and three of the strips have the number 3 written on them. What is the probability of randomly pulling a strip with the number 4 written on it followed by pulling a strip with the number 3 written on it?

The probability is 1/12

Step-by-step explanation:

Mathematically, the probability of pulling pulling a strip with the number 4 written on it followed by pulling a strip with the number 3 written on it = Probability of pulling a strip with the number 4 written on it * Probability of pulling a strip with the number 3 written on it

The probability of pulling a strip with number 4 written on it = number of strips with number 4 written on it/total number of strips

Number of strips with number 4 = 4

Total number of strips = 3 + 4 + 5 = 12

Thus the probability = 4/12 = 1/3

The probability of pulling a strip with number 3 written on it = number of strips with number 3 written on it/total number of strips = 3/12 = 1/4

Thus , the probability of pulling pulling a strip with the number 4 written on it followed by pulling a strip with the number 3 written on it = 1/3 * 1/4 = 1/12

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
