Probability of Getting a Learned Question

To calculate the probability of getting a learned question out of a total of 80 questions, we need to know the number of questions the student has learned. In this case, the student has learned 7 questions.

The probability of getting a learned question can be calculated using the formula:

Probability = (Number of learned questions) / (Total number of questions)

Substituting the values, we get:

Probability = 7 / 80

Calculating this, we find that the probability of the student getting a learned question is approximately 0.0875, or 8.75%.

Please note that this calculation assumes that all questions have an equal chance of being selected and that the student's knowledge of the questions is accurate.
