Suppose a special 15-sided die is rolled once where each face is marked with a number 1 through 15. What is the probability that the die lands on a 8 or a 12?
Question
Suppose a special 15-sided die is rolled once where each face is marked with a number 1 through 15. What is the probability that the die lands on a 8 or a 12?
Solution
The probability of a single event in a probability experiment can be found using the formula:
P(E) = Number of favorable outcomes / Total number of outcomes
In this case, the total number of outcomes is 15 (since the die has 15 sides, each with a different number).
The favorable outcomes are rolling an 8 or a 12. There are 2 favorable outcomes.
So, the probability P(E) of the die landing on an 8 or a 12 is:
P(E) = 2 / 15
So, the probability that the die lands on an 8 or a 12 is 2/15.
