Title: Probability of one or two events

Learning Objectives
Grade F

To be able to calculate the probability of outcomes of single events and understand that the probability scale runs from 0 to 1.

What is the probability of rolling a odd number of a die?

Grade E
To be able to calculate the probability of an event happening when you know the probability that the event doesn’t happen and knowing when you cannot use this rule.


What is the probability of picking a red counter from a bag if you know the probability of not picking it is 0.65?
