I need help with (half way done

which probability symbols do I use for each one 'P(R)="

7.Drawing a yellow marble, given that a red marble was drawn on the first draw and not replaced?

Answer 1

The probability of drawing a blue marble will be 1/3.

How to calculate probability?

Blue marbles = 3

Red marbles = 2

Yellow marbles = 4

Total marbles = 3 + 2 + 4 = 9

The probability of drawing a blue marble will be:

= 3/9

= 1/3

The probability of drawing a marble that isn't red will be:

= 3/9 + 4/9

= 7/9

The probability of drawing a red and yellow marbles will be:

= 2/9 + 4/9

= 2/3
