Final answer:
The probability that Keisha chooses an orange marble from the bag is 2/15.
Step-by-step explanation:
The question asks about the probability of Keisha choosing an orange marble from a bag. To calculate this, we need to consider the total number of marbles and the number of orange marbles. The bag contains 3 red, 2 orange, 1 teal, 2 purple, 4 blue, and 3 white marbles, making a total of 15 marbles. The probability of drawing an orange marble is the number of orange marbles (2) divided by the total number of marbles (15).
The probability can be calculated as follows:
Probability = (Number of orange marbles) /(Total number of marbles)
Probability = 2/15
The probability that Keisha will choose an orange marble is 2/15.
