An urn contains 4 purple marbles and 3 pink marbles. Two marbles are drawn at random. What is the probability that both marbles are purple
if drawn with replacement?


Sagot :

Answer: 16/49

Step-by-step explanation:

The probability of pulling a purple marble is 4/7, since 4+3 is 7.
Since the marbles are replaced, the probability does not change when pulling out marbles.

To combine probabilities, we multiply them

[tex]\frac{4}{7} * \frac{4}{7} = \frac{16}{49}[/tex]

Step-by-step explanations

possibility=4+3=7

4/7=4/7
