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

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

a) 32pie square meters

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
