Sure! I can explain how to find the percentage and probability.
To find the percentage, you need to divide a part of a whole by the whole and then multiply the result by 100. The formula is:
Percentage = (Part / Whole) x 100
For example, let's say you want to find the percentage of students who passed an exam. If there are 80 students in total and 60 of them passed, you would calculate it like this:
Percentage of students who passed = (60 / 80) x 100 = 75%
So, the percentage of students who passed the exam is 75%.
Now, let's talk about probability. Probability measures the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. To find the probability, you divide the number of favorable outcomes by the total number of possible outcomes.
The formula for probability is:
Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes)
For example, let's say you want to find the probability of rolling a 6 on a fair six-sided die. Since there is only one favorable outcome (rolling a 6) and six possible outcomes (numbers 1 to 6), you would calculate it like this:
Probability of rolling a 6 = 1 / 6 ≈ 0.1667
So, the probability of rolling a 6 on a fair six-sided die is approximately 0.1667 or 16.67%.
I hope this explanation helps you understand how to find the percentage and probability!
