What is the probability of rolling a odd number of a die?
Grade E
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?
To be able to calculate all the outcomes of two independent events (such as tossing a coin & throwing a dice) and calculate probabilities from lists or tables
What is the probability of throwing a total of 7 on two dice?

Simple Probability
Simple probability is all about finding the probability of one event with equally likely outcomes ie. I roll a 4 on a normal 6-sided die.
To remind yourself how to do this see - BBC Bitesize - Simple Probability now test your understanding here - BBC Bitesize - Self Assess

If you think you need more practice on these topics do the following questions in your book - Ten Ticks - 5, 1, pages 39-40 you can find the answers here.
On your iPad you can test your understanding of probability using this sorting activity - Stick on Maths - Probability (iPad only)

These questions should be completed in your book and are no more difficult however be careful as the questions are put into a context ie. real life examples - Ten Ticks - 6, 6, pages 22-23 you can find the answers here.
Probabilities Add to 1
You know that if you take the probability of all possible events they will add to 1. For example if you throw a coin P(Head) = 0.5, P(Tail) = 0.5 and then 0.5 + 0.5 = 1.
