It's obviously hair that I'm talking about(if you couldn't tell) but I've been trying to do this question now and for the life of me I cannot remember how to figure it out so any help on how to do it would be nice.

You're already given the probabilities of the different hair colours. The fact that there is 3000 people doesn't make a difference.
Therefore, the probability of having black hair is 33% or 0.33.
The number of people with black hair is 0.33*3000 = 990.
The ratio of people with black hair is 990/3000 = 33/100

Since 33% of the 3000 people have black hair, then the probability of one of the people (picked at random from the 3000 people) having black hair is 33% or 33 chances out of a hundred.

(33% of people have black hair) x (3000 total people)
.33*3000=990 people have black hair

.33 / 3000 or 33%

33% (or .33) * 3000 = 990

none ...cause 35+33+32=100%

you already have the percentage...
35%=.35
Probability is
.35:.65
or
.54:1
