Question

Nick selects a counter at random 400 times and records the number of times the counter is green, black, purple or red. Green(80) Black(120) Purple(80) Red(120) Work out the relative frequency of landing on green.​

Answer 1

The relative frequency of landing on green can be calculated by dividing the number of times the counter landed on green by the total number of trials (400):

Relative frequency of green = Number of times landed on green / Total number of trials

Relative frequency of green = 80 / 400

Relative frequency of green = 0.2

So, the relative frequency of landing on green is 0.2, which can also be expressed as 20%.
