Question

A drawer contains 3 red paper clips 5 green paper clips and 4 blue paperclips one paper clip is taken from the drawer then replaced another paper clip is taken from the drawer what is the probability that the first paper clip is red and the second paper clip is blue?

Answer 1

Answer:

3/12 for red

4/12 for blue

Step-by-step explanation:

3 is red

5 is green

4 is blue

3 + 5 + 4 is 12 so it is out of 12 altogether

3/12 for red

4/12 for blue

Answer 2

Answer:

1/12

Step-by-step explanation:

To find the probability of the event occuring, we need to find the probabilites of taking a red paperclip and taking a blue paperclip and then multiply them together.

Red paperclip:

3/12 = 1/4

Blue paperclip:

4/12 = 1/3

Probability of event:

3/12 x 4/12 = 12/144 = 1/12

1/4 x 1/3 = 1/12
