Jeat is growing carrots from seed in his garden. He plants 28 carrot seeds but only 12 grow.
Jeat says The probability of one of my carrot seeds growing is
Use Jeat’s result to show that he is correct.
[1]
A farmer uses this probability to calculate how many carrot seeds he should plant to grow 10 000 carrots.
How many seeds should he plant?
[2]
Explain why it may not be sensible for the farmer to use Jeat’s experimental probability to calculate the number of seeds he should plant.

A company makes sweets. The sweets are put into packets.
Here are some facts.
Calculate the mean number of sweets in one packet.
[2]
Sweets are made on 288 days each year.
Calculate the number of sweets made each year. Give your answer in standard form.
[3]
The company has 152 machines making the sweets. Each machine operates for 15 hours each day.

Two bags each contain only red counters and yellow counters.
In Bag A, the ratio of red counters to yellow counters is 1: 4.
Sharon says
The proportion of the counters that are red is the same in both bags.
Explain why Sharon is not correct.
[1]
The number of counters in the two bags is the same.
Complete the table below to show how many counters of each colour could be in the bags.
[3]
In another bag, Bag C, the ratio of red counters to yellow counters is 3: 4. If 3 of the red counters are removed from Bag C, the ratio of red counters to yellow counters is 3: 5.
How many yellow counters are in Bag C?
