Answer 2

Calculating Probability of Getting a Question on Acids in Chemistry Exam

To calculate the probability of a student getting a question on the topic "Acids" in a randomly chosen exam ticket, we can use the following formula:

Probability (P) = Number of favorable outcomes / Total number of possible outcomes

In this case, the number of favorable outcomes is the number of tickets with questions on the topic "Acids," and the total number of possible outcomes is the total number of tickets in the exam.

Calculation

Given: - Total number of tickets in the exam = 15 - Number of tickets with questions on the topic "Acids" = 6

Using the formula: Probability (P) = 6 / 15

Result

The probability of a student getting a question on the topic "Acids" in a randomly chosen exam ticket is: Probability (P) = 6 / 15

Therefore, the probability is 6/15 or 0.4 (or 40%).

This means there is a 40% chance that a student will get a question on the topic "Acids" in a randomly chosen exam ticket.
