A spinner is numbered 1- 5. A die ( ) is numbered 1-6. Sara says she has more chance of getting an odd number with the spinner. Is she correct? Explain your answer.
Answer: No, because she's not a mind reader. How does she know what's going to come up?
Don't you just love how their minds work?

Compared to a Year 10 or 11 pupil ... Jo has a spinner with the numbers 1 , 3 , 5 , 7 , 9 , 10 and 11 on it. What is the probability of gettin an odd number?
Answer: "well a number can be either odd or even, so it's 50/50 innit"
Same with the lottery ... you can either win the jackpot or not, so it's 50/50 again!!
