GCSE Secondary Maths Age 13-17 - Probability & Statistics: Independent Events - Explained

The video tutorial explains the concept of probability, focusing on the likelihood of two students, Sanay and Jaden, being late for school. Alfie calculates the joint probability of both being late by multiplying their individual probabilities, assuming the events are independent. The teacher clarifies that independence means one event does not affect the other, using examples to illustrate this. The tutorial concludes by emphasizing that multiplying probabilities is valid only for independent events.

What is the probability that Sanay is late for school tomorrow?

What is the probability that Jaden is late for school tomorrow?

What assumption has Alfie made regarding the probabilities of Sanay and Jaden being late?

Explain what it means for two events to be independent in the context of this scenario.
