Help me study for my Mathematics class. I’m stuck and don’t understand.

**1. Find the indicated probability.**

**
**

On a multiple choice test, each question has 6 possible answers. If you make a random guess on the first question, what is the probability that you are correct?

2. **Find the indicated probability.**

**
**A die with 12 sides is rolled. What is the probability of rolling a number less than 11?

3. **Find the indicated probability.**

**
**A bag contains 6 red marbles, 3 blue marbles, and 5 green marbles. If a marble is randomly selected from the bag, what is the probability that it is blue?

4. **Find the indicated probability.**

**
**Two 6-sided dice are rolled. What is the probability that the sum of the two numbers on the dice will be 3?

5. Find the odds against correctly guessing the answer to a multiple choice question with 6 possible answers.

6. **Find the indicated probability.**

**
**A spinner has equal regions numbered 1 through 15. What is the probability that the spinner will stop on an even number or a multiple of 3?

7. **Find the indicated probability.**

**
**If you pick a card at random from a well shuffled deck, what is the probability that you get a face card or a spade?

8. **Find the indicated probability.**

**
**In one town, 44% of all voters are Democrats. If two voters are randomly selected for a survey, find the probability that they are both Democrats. Round to the nearest thousandth if necessary.

9. **Find the indicated probability.**

**
**Find the probability of correctly answering the first 3 questions on a multiple choice test if random guesses are made and each question has 6 possible answers.

10. **Find the indicated probability.**

**
**A manufacturing process has a 70% yield, meaning that 70% of the products are acceptable and 30% are defective. If three of the products are randomly selected, find the probability that all of them are acceptable.
