Suppose a jar contains 13 red marbles and 33 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

7.5%

Step-by-step explanation:

Although they tell us that they are held at the same time, there is no difference between taking out first and then another, because the marbles DO NOT have a replacement.

So the final probability would be:

Total marbles 13 + 33 = 46

The probability of drawing a red would be: 13/46, on the first attempt.

In the second half it would be: 12/45, because we have one less marble and I specify a red one.

Therefore, the final probability is the multiplication of both events, like this:

P = (13/46) * (12/45) = 0.075

In other words, the probability of this happening is 7.5%.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
