ella [17]

Answer:

P(Red) = 0.44

Step-by-step explanation:

The question required a tree diagram (see attachment)

Required

Determine P(Red)

To do this, we simply each path that leads to red on the attached tree.

So, we have:

Red\ 1 = 0.35 * 0.6

Red\ 2 = 0.45 * 0.2

Red\ 3 = 0.20 * 0.7

P(Red) is then calculated as:

P(Red) = Red\ 1 + Red\ 2 + Red\ 3

P(Red) = 0.35 * 0.6 + 0.45 * 0.2 + 0.20 * 0.7

P(Red) = 0.44

<em>Hence, the probability of selecting Red is 0.44</em>
