Color Number of Marbles
Blue 4
Black 2
Red 5
Orange 4
Green 5
Rachel has 20 marbles in a jar. This table shows the number of blue, black, red, orange, and green marbles. What is the probability that if she randomly drew a marble out of the jar it would be orange?
4/20 = 1/5
1\5
1/5
To find the probability that Rachel randomly draws an orange marble, we need to divide the number of orange marbles by the total number of marbles in the jar.
According to the table, Rachel has 4 orange marbles.
To find the total number of marbles in the jar, we sum up the number of marbles for each color:
4 + 2 + 5 + 4 + 5 = 20
So, the total number of marbles in the jar is 20.
Now, we can calculate the probability of drawing an orange marble:
Probability = Number of orange marbles / Total number of marbles
Probability = 4 / 20
Simplifying the fraction, we get:
Probability = 1/5
Therefore, the probability that Rachel randomly draws an orange marble is 1/5 or 0.2, which is equivalent to 20%.
