Probability Carnival Games

You enter a raffle by putting tickets with your name in a bin to draw from. There are 100 tickets total in the bin, and 15 have your name on them. If they draw three winners, what is the probability that you do not win any of the raffle prizes?

Write your answer as a decimal rounded to three decimal places.

Next you decide to go to the duck pond.  A revolving river of 30 rubber ducks floats by.  Each duck has a colored sticker on the bottom.  Eight of the ducks have red stickers, ten have green stickers, and twelve have blue stickers.

If you draw three ducks in a row that are red (without putting the first two back in), you win a large prize. What is the probability of winning a large prize?

Your best friend asked you to accompany him to a carnival to play games of chances. According to him, his horoscope states that he is so lucky that day and he wants to try his luck at the carnival. How will you convince him not to go to the carnival?

• I will ask him to review very well his notes on probability so that he can apply them to a real-life situation like this.

• I will tell him that what is written in the horoscope is sometimes true and sometimes false so he would rather not go to the carnival.

• I will give him instances wherein he could see the real picture of having a very little chance of winning so    that he will not be wasting his money and time.

• I will convince him not to go to the carnival this time because we have to finish first our project in Probability. Anyway, there will be other time to go and enjoy all the games there.

What is missing in the formula of Theoretical Probability;

• number of events

• number of all possible outcomes

• number of favourable  outcomes

• number of times of an event occurs

It is an event which has a single outcome.

• simple event

• compound event

• experiment

• single event

Students standing in line for a theme park were surveyed about their favorite ride. Their responses are shown below. If one student is picked randomly, then which of the following is true?

• The student’s favorite ride is half as likely to be a live show than a roller coaster.

• The student’s favorite ride is more likely to be a carnival game than a roller coaster.

• The student’s favorite ride is twice as likely to be a roller coaster than the carnival games.

• The student’s favorite ride is twice as likely to be the carnival game than the live show.

The spinner below is spun two times in a row. What is the probability of spinning two prime numbers?

• 9/64

• 1/4

• 25/64

• 1/2
