An urn contains 4 purple marbles and 3 pink marbles. Two marbles are drawn at random. What is the probability that both marbles
Archy [21]

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

\frac{4}{7} * \frac{4}{7} = \frac{16}{49}

Allushta [10]

Answer:

Step 4

Step-by-step explanation:

Tasha was correct in all the steps leading up to the fourth one. However, in the fourth step was where she messed up.

She said that: \frac{1}{256} =-\frac{1}{4^{-4}}=4^{-4}

However, when we have a negative exponent, in order to get rid of the negative, we simply take the reciprocal of the number and then make the exponent positive. Here, the answer should be:

\frac{1}{256} =\frac{1}{4^{4}}=4^{-4}
