Question

A jar holds 15 red pencils and 10 blue pencils. One pencil is chosen and the replaced. A second pencil is then chosen. What is the probability of drawing two red pencils from the jar?

Answer 1

multiply the probabilities together.
probability first one is red is \(\frac{15}{25}=\frac{3}{5}\) and probability second one is red is also \(\frac{3}{5}\) so your job is to compute
\[\frac{3}{5}\times \frac{3}{5}\]

Answer 2

So it does not change since it was replaced?

Answer 3

it does not change because you have 15 red pencils and 25 total for both draws
yes, because it was replaced

Answer 4

Thank you!
