The diagram below shows the contents of a jar from which you select marbles at random.
An illustration of a jar of marbles is shown. Four of the marbles are labeled with an upper R, seven of the marbles are labeled with an upper B, and five of the marbles are labeled with an upper G. The key identifies upper R to represent red marbles, upper B to represent blue marbles, and upper G to represent green marbles.
Unfortunately, it seems that the question is missing. Please provide me with the question so I can assist you in a better way.
the question is: what is the probability of selecting a red marble then another red marble
There are 16 marbles in the jar, 4 of which are red.
The probability of selecting a red marble on the first draw is therefore 4/16 or 1/4.
Assuming the first marble is not replaced, there are now 15 marbles in the jar, 3 of which are red.
The probability of selecting a red marble again on the second draw is therefore 3/15 or 1/5.
To find the probability of both events occurring, you multiply the probabilities together:
1/4 x 1/5 = 1/20
Therefore, the probability of selecting a red marble followed by another red marble is 1/20.
To find the answer to this question, we need to determine the probability of selecting a particular color marble from the jar.
Let's start by calculating the total number of marbles in the jar. From the given information, there are 4 red marbles, 7 blue marbles, and 5 green marbles. So, the total number of marbles is:
Total marbles = 4 (red marbles) + 7 (blue marbles) + 5 (green marbles)
Total marbles = 16 marbles
Now, let's calculate the probability of selecting a red marble.
Probability of selecting a red marble = Number of red marbles / Total number of marbles
Probability of selecting a red marble = 4 / 16
Probability of selecting a red marble = 1/4
Similarly, we can calculate the probability of selecting a blue marble and a green marble:
Probability of selecting a blue marble = Number of blue marbles / Total number of marbles
Probability of selecting a blue marble = 7 / 16
Probability of selecting a green marble = Number of green marbles / Total number of marbles
Probability of selecting a green marble = 5 / 16
Now, you can write down the calculated probabilities for selecting each color marble in the given space:
Probability of selecting a red marble: 1/4
Probability of selecting a blue marble: 7/16
Probability of selecting a green marble: 5/16
