The table below shows the number of marbles of different colors in a box. A fair coin is shown below the table.
andrezito [222]
First we need to find the probability of selecting the 1 blue marble out of the 20 marbles total, which is 1/20.

Next, we need to find the probability of tossing the fair coin so it lands tails up, which is 1/2.

To find the probability of both events happening, we need to multiply the probabilities of the two individual events:
1/20 * 1/2 = 1/40

So the answer is 1/40, or 2.5%

Sorry about the poor formatting :( I'm on my phone at the moment, which makes it difficult.

Hope I helped, and let me know if you have any questions :D
