What is conditional, and identity or a contradiction ?
in terms of a linear equation.
Please can you give some examples

Assume that the box contains 12 balls:
5 red, 3 blue, and 4 yellow. As in the text, you draw one
ball, note its color, and if it is yellow replace it. If it is not yellow
you do not replace it. You then draw a second ball and note its color.
(1) What is the probability that the second ball drawn is yellow?
(2) What is the probability that the second ball drawn is red?
