There are 3 Red, 1 Blue and 2 Yellow marbles in a bad once a marble is selected, it is replaced. what is the probability of picking a red and yellow marble

16.7%.

Step-by-step explanation:

In this case, we know that although the marble is selected, it is replaced, that is, the total value of marbles never changes.

We know that in total there are 6 (3 + 2 + 1)

The probability of drawing a red is:

3/6

The probability of getting a yellow is:

2/6

Therefore the probability of drawing a red and a yellow is:

3/6 * 2/6 = 6/36 = 1/6 = 0.167

In other words, the probability of this happening would be 16.7%.

this doesn't make sense lol

no not all of them.

step-by-step explanation:

some of them have a square base.
