Question

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?

Answer 1

Step-by-step explanations

possibility=4+3=7

4/7=4/7

Answer 2

Answer: 16/49

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

`(4)/(7) * (4)/(7) = (16)/(49)`
