A bag contains 3 blue marbles and 2 red marbles. A marble is taken from the bag at random and then replaced. A second marble is then taken from the bag. What is the probability that the two marbles were different colors? Give your answer as a fraction.

This is simple,

So first we set this problem up

2 Red + 3 Blue + 7 Green = 12 Total Marbles

The formula for calculator probability is

# of favorable outcomes / # of possible outcomes

The number of favorable outcomes we have is 3 because we are trying to find the probability of pulling out a blue marble

The number of possible outcomes is 12 because we have 12 total marbles

3/12 simplifies to 1/4 which is .25

The probability of drawing a blue marble is 0.25 or 25%

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
