MTTC 103 Elementary Practice 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What information do students need to find the probability of pulling a red gumball from a jar?

How many green gumballs are in the jar?

How many different colors of gumballs are in the jar?

How many red gumballs are in the jar?

To find the probability of pulling a red gumball from a jar, students need to know how many red gumballs are actually in the jar. Probability is calculated by taking the number of successful outcomes, in this case, the number of red gumballs, and dividing it by the total number of outcomes, which is the total number of gumballs in the jar. Therefore, without knowing the quantity of red gumballs present, students cannot accurately determine the probability.

The overall context of understanding probability involves recognizing that success (pulling a red gumball) must be compared to all possible outcomes (the entire contents of the jar). Other information about the count of gumballs of different colors or their duration in the jar does not directly impact the calculation for red gumballs.
