Should schools be allowed to determine when their own school holidays are and how long they last for?*
- Yes, the school is responsible for the children and their learning so should be allowed to decide how long holidays can be when children are not progressing with schoolwork.
- Yes, schools are made up of different compositions of religions around the country so schools can organise holidays to best suit the cultural holidays of the children attending the school.
- No, this would be very hard for parents with children at different schools as they may not be able to go on a summer holiday if the holiday times do not overlap.
- No, holidays need to be standardised across the country so that all children get the same amount of time in education and can adequately cover the syllabus.

Daisy is playing a game called hook the duck at the funfair. There are 25 ducks in the pool, each with a different coloured sticker on the underside. Red denotes no prize, blue a small prize and green a large prize. There are 12 ducks with a red sticker, 10 with a blue sticker and 3 with a green sticker. In each go Daisy can hook 3 ducks. On her first turn, Daisy gets two ducks with red stickers and one duck with a green sticker. Should Daisy return all 3 ducks to the pool before playing again, to maximise her chance of getting another duck that will win her a prize?*
- Yes, this will mean 13 winning ducks in the pool compared to 12 if she does not
- Yes, she should return them so that there are 3 big prize-winning ducks compared to 2 if she does not return them
- No, now she has 12/22 ducks that are winning, which is a higher proportion than 13/25 therefore she is more likely to win a prize if she does not return them
- No, she has eliminated 1 duck that is not winning so shouldn’t

Ben is picking out socks to wear early in the morning. It is very dark so he cannot see what colour socks he is picking. In his sock draw, he has 4 pairs of black socks, 2 pairs of blue socks and 1 pair of green socks, but they are not folded in pairs. Should Ben pick 4 socks in order to guarantee having 2 socks of a matching colour?*
- Yes, this is the fewest number of socks he can draw to guarantee a matching pair as he may draw 3 socks of different colours, but the 4th will have to match one
- Yes, he has a 100% chance of picking 2 black socks if he draws 4 socks
- No, he could pick 2 socks and have a matching pair, no need to draw 4
- No, there are more than double the number of black socks as any other colour so he is statistically likely to draw 2 black socks first
