A spinner is spun 800 times.
The probabilities it lands on each colour are shown below.
The probability it lands on red is the same as the probability it lands on yellow.

Colour Red Green Brown Yellow
Probability 0.3 0.54
How many times would you expect it to land on each colour?

Does the 0.3 and 0.54 apply to the green and brown?

Okay, so probability is always out of 1, so 0.3+0.54=0.84, which means there is 0.16 probability it will land on either red or yellow.
Seems red and yellow have the same probability, 0.16/2=0.08

So to find the amount of times it would land on red, it is 0.08*800
Green it is 0.3*800
Brown is 0.54*800
And yellow would be the same as red
