MATHS - Statistics - Probability Part 1

The video tutorial introduces the concept of probability, explaining it as a measure of the likelihood of an event occurring, ranging from 0 to 1. It discusses constructing sample spaces for various experiments, such as coin flips and dice rolls, and demonstrates how to calculate probabilities using examples like card decks and colored balls. The tutorial concludes by highlighting the importance of probability in predicting outcomes over repeated experiments, referencing the law of large numbers.

What is the range of values that probability can take?

• 0 to 100

• 0 to 10

• 0 to 1

• 1 to 100

How many different outcomes are there when flipping two coins?

• 2

• 3

• 4

• 5

What is the probability of getting a sum greater than 9 when rolling two dice?

• 1/6

• 1/3

• 1/2

• 1/4

If you draw one card from a standard deck, what is the probability of it being a spade or an ace?

• 1/2

• 1/4

• 1/3

• 4/13

According to the law of large numbers, what happens when you repeat an experiment many times?

• The outcomes become less predictable

• The probability of success increases

• The ratio of successful outcomes approaches the calculated probability

• The probability of success decreases
