Slide 4 : Example: Flipping a coin
What’s the probability of getting heads when flipping a coin? Ans: There is only one way to get heads in a coin toss. Hence, the top of the probability fraction is 1. There are two possible results: heads or tails. Forming the probability fraction gives 1/2.
Example: Tossing a die
What’s the probability of getting a 3 when tossing a die? Ans: A die (a cube) has six faces, numbered 1 through 6. There is only one way to get a 3. Hence, the top of the fraction is 1. There are 6 possible results: 1, 2, 3, 4, 5, and 6. Forming the probability fraction gives 1/6.
Example: Drawing a card from a deck
What’s the probability of getting a king when drawing a card from a deck of cards? Ans: A deck of cards has four kings, so there are 4 ways to get a king. Hence, the top of the fraction is 4. There are 52 total cards in a deck. Forming the probability fraction gives 4/52, which reduces to 1/13. Hence, there is 1 chance in 13 of getting a king.
Example: Drawing marbles from a bowl
What’s the probability of drawing a blue marble from a bowl containing 4 red marbles, 5 blue marbles, and 5 green marbles? Ans: There are five ways of drawing a blue marble. Hence, the top of the fraction is 5. There are 14 (= 4 + 5 + 5)possible results. Forming the probability fraction gives 5/14.
