Emma is playing a spinning game using the spinner shown. She gets one spin and needs green to win. What's probability that she will NOT win?

• .25
• .75
• .70
• 40

Multiple Choice

Which event is least likely to occur?

• spinning a 3 on a spinner divided into 3 equal sections numbered 1-3

• rolling an even number on a number cube that has sides numbered 1-6

• tossing a fair coin and landing on heads

• picking a green marble from a bag that contains 2 orange, 10 green, and 7 purple

Likelihood

How likely is something?

• Likelihood is expressed as a fraction or a decimal from 0 to 1.

• 0 means that the event is impossible

• In between 0 and 1/2 or 0.5​ means the event is unlikely to happen.

• In between 1/2 or 0.5 and 1 means the event is likely to happen.

• 1 means that the event will happen every time​

​How to build a probability

Probability is a way to put a number on how likely an event is. The easiest way to build a probability is as a fraction.

• In the numerator put the number of times the event gives​ the results that you desire.

• In the denominator put the total number of possible outcomes.​

Probability

​Example: How to build a probability

​There is a bag with 10 marbles; 5 blue, 3 red, and 2 green. What is the probability of picking out a red marble?

• Start with the denominator - how many total marbles? 10

• Then count up how many total are the desired color, red? 3

• Build a fraction. How many of what you are looking for over the total number.​

• 3 red out of 10 total or 3/10​

Multiple Choice

LEVEL 4 - You are looking for the experimental probability of a coin landing on tails. Without knowing the results, which experimental probability should be more accurate? Explain.

a. Flipping a coin 10 times and recording how many times it lands on tails.

b. Flipping a coin 100 times and recording how many times it lands on tails.

• Flipping a coin 10 times because it has less experiments.

• Flipping a coin 10 times because it won't take as long.

• Flipping a coin 100 times because it has more experiments.

• Flipping a coin 100 times because 100 can be divided by more numbers than 10.
