Happy meal Simulation

Why did Aroha decide to buy a Happy meal a day for up to 2 weeks?

• In order to collect all the toys

• In order to run a simulation

• In order to collect 3 specific toys

Why did Aroha stop buying Happy Meals?

• the 2 weeks had finished or she had collected the 3 toys she wanted

• she gave up

• she ran out of money

• she had completed all 50 simulations

In how many of the 50 simulations was Aroha successful at acquiring all 3 toys?

• all

• none

• 19

• 60

How can you tell when Aroha has been successful in a particular simulation?

• all 3 colours appear

• you can add the numbers

• Google sheets can calculate it

• you can't tell from the spreadsheet

What is the maximum number of Happy meals she bought?

• 50 x 14 = 700

• 14

• 10

• 50

Which function do you use to colour the numbers?

• randomise

• colourcode

• conditional formatting

What is the correct formula for generating a random number between 1 and 10?

• randombetween(1,10)

• =randbetween(1,10)

• =ranbetween[1,10]

• =random(1/10)

Everytime you press a key, new random numbers are generated by the randbetween function. How can you stop this from happening?

• copy and then delete the number

• copy the number and then use press Window + Q

• copy the number and then use special paste > value only

Why do we colour the numbers?

• to allow us to see if all 3 toys are present in a simulation

• it looks much prettier

• conditional formatting

• this is a type of graph

Why do we need to run the simulation 50 times?

• to gather a larger sample size of outcomes

• so we can have confidence in the reliability of the results

• it gives us a clearer understanding of the system we are simulating

• all of the above
