You have a jar of 50 colored marbles. The distribution of marbles by color is shown in the table below. You take one marble out at random. What is the probability that the marble is not blue? Do not round your answer. Write your answer in decimal form, not as a fraction or percent. red, yellow, green, blue= 42%, 16%, 10%, 32%

Suppose a jar contains 7 red marbles and 32 blue marbles. If you reach in the jar and pull out one marble at random, do not replace the marble, and reach in the jar to pull out a second marble. Find the probability that both are red. Write your answer as a reduced fraction
a jar contains 5 red, 10 blue, and 7 green marbles. three marbles are selected, color is noted, and replaced in the jar. Find the following probabilities. a) getting 2 blue marbles and a green marble b)getting a red, blue, and green marble
Suppose a jar contains 12 red marbles and 30 blue marbles. If you
reach into the jaw and pull out 2 marbles at random at the same
time, find the probability that they are both red. Enter the answer

What is the probability of drawing a green marble?
A marble is selected at random from a jar containing 5 red marbles, 4 yellow marbles, and 3 green marbles. What is the probability that a) the marble is red? b) the marble is not yellow? c) the marble is either red or green? d) the marble is neither red nor green?
A jar contains 4 red marbles numbered 1 to 4 and 7 blue marbles numbered 1 to 7. A marble is drawn at random from the jar. a) Find the probability that the marble is red or odd-numbered. Enter your answer as a percent, rounded to the nearest tenth of a percent. b) Find the probability that the marble is blue, given that the marble is even-numbered. Enter your answer as a percent, rounded to the nearest tenth of a...
You reach into a bag that contains the following distribution of colored marbles: 5 green, 8 yellow, 3 purple. You will grab 2 marbles one at a time. a. (1pt) Find the probability that you first select a green and second a yellow marble. b. (1pt) Find the probability that you select no green marbles in your two picks. c. (lpt) Find the probability that you select exactly 1 purple marble and one non-purple marble.
Use a probability tree to answer the following. A jar contains 7 red marbles, 7 green marbles, and 7 blue marbles. What is the probability that you draw a red marble? = What is the probability that you choose exactly one of each color, if you pick 3 from the jar? = What is the probability that you draw 4 green marbles in a row if you do not replace the marbles after each draw? =
Suppose an opaque jar contains 7 red marbles and 10 green marbles. The following exercise refers to the experiment of picking two marbles from the jar without replacing the first one. What is the probability of getting a green marble first and a red marble second? (Enter your probability as a fraction.) this problem is posted on your page, however, the answer is incorrect. Thank you!
A jar contains 5 red marbles numbered 1 to 5 and 12 blue marbles numbered 1 to 12. A marble is drawn at random from the jar. Find the following probabilities. Enter your answer as a percent, rounded to the nearest tenth of a percent. Hint: Create the sample space first. R1 may represent 1st red marble, B1 may represent 1st blue marble, etc c) The probability that the marble is blue, given that the marble is even-numbered: d) The...
