The domain of the function is all the values from which the functio can be mapped: here it's between 0 and <span>76,867 -depending on how many people come
</span>
The range is all the values that the function can have.So here it's from 0, when noone is coming, to 76867*161=12377036
Total number of marble = 10
3green
2red
5 blue
Probability that the first marble is red = 2/10
Probability that the second is blue = 5/9(a reduction in the total number of marbles, because after the first marble was picked it wasn't replaced)
Probability of 1st and 2nd being red and blue respectively = 2/10 × 5/9
=1/9....
Hope this helped...?
