Understanding Probability and Fractions

The video tutorial explains how to calculate the probability of landing on a specific number using a spinner. It covers determining the total and favorable outcomes, converting probabilities from fractions to decimals and percentages, and understanding probability intervals. The tutorial concludes with a discussion on the likelihood of events based on their probability values.

What is the first step in determining the probability of an event?

• Identify the total number of outcomes

• Count the number of favorable outcomes

• Multiply the outcomes by 100

• Convert the probability to a percentage

How many total outcomes are there when using the spinner?

• Seven

• Nine

• Six

• Eight

What is the probability of landing on a three expressed as a fraction?

• 1/8

• 1/6

• 1/4

• 1/2

How do you convert a fraction to a decimal?

• Divide the numerator by the denominator

• Multiply the fraction by 100

• Subtract the denominator from the numerator

• Add the numerator and denominator

What is the decimal equivalent of 1/8?

• 0.125

• 0.5

• 0.25

• 0.375

What does a probability of 1/8 imply about the expected outcome?

• Five out of every eight spins will land on a three

• Three out of every eight spins will land on a three

• Seven out of every eight spins will land on a three

• One out of every eight spins will land on a three

What is the probability range for any event?

• 0 to 1

• 1 to 2

• 0.5 to 1

• 0 to 0.5

If an event has a probability of 0, what does it mean?

• The event is impossible to occur

• The event is unlikely to occur

• The event is certain to occur

• The event will occur half the time
