Question

A box of matching game pieces contain a red pieces five green pieces seven yellow pieces you reach in and randomly take out one piece and then a second piece what is the probability of drawing a green Peace followed by a red piece

Answer 1

Answer:

5/156

Step-by-step explanation:

First, how many pieces?

1 red+ 5 green + 7 yellow = 13 pieces

We draw a piece

The probability it is green

P(green) = number of green/ total

              = 5/13

Now there are only 12 pieces left

Probability the second piece drawn is red

P(red with 1 piece removed) = number of red/ total left

           = 1/12

P(green, then red) = P(green) * P(red with 1 piece removed)

                               = 5/13 *1/12

                                =5/156
