Question:

A bag contains three red and four white balls.

If one ball is taken at random and then replaced, and another ball is taken calculate the following probabilities:

(a) P(first ball red and second ball red)

(b) P(just one red)

Figure 3.6 displays the experiment in a tree diagram.

Each branch of the tree indicates the possible result of a draw and associated probabilities.
