Calculating Probability: Equally Likely Possibilities, Mutually Exclusive and Independent Events

The video tutorial covers the basics of calculating probability, focusing on equally likely outcomes. It explains the formula for probability and provides examples using a spinner and cards. The tutorial also discusses mutually exclusive and independent events, illustrating how to calculate probabilities for these scenarios. The video concludes with a recap of the key concepts and encourages practice.

What is the probability of spinning a 1 on a spinner with 8 sections, 3 of which are numbered 1?

• 1/8

• 3/8

• 1/4

• 5/8

If a spinner has 8 sections and 2 are numbered 2, what is the probability of landing on a 2?

• 2/8

• 1/8

• 1/4

• 3/8

How do you calculate the probability of either spinning a 1 or a 2 on a spinner?

• Subtract their probabilities

• Add their probabilities

• Multiply their probabilities

• Divide their probabilities

In the word 'statistics', what is the probability of picking a T from 10 cards?

• 1/10

• 2/10

• 3/10

• 1/5

What is the probability of flipping a heads on the first coin and tails on the second coin?

• 1/2

• 1/4

• 1/8

• 1/16

If you pick a card and then replace it, what is the probability of picking a T and then an I from the word 'statistics'?

• 2/10

• 3/10

• 1/5

• 6/100

What is the formula for calculating the probability of independent events A and B both occurring?

• Multiply their probabilities

• Divide their probabilities

• Add their probabilities

• Subtract their probabilities
