Using it's concept, considering the tree diagram, the probability of event C is given as follows:
P(C) = 0.26.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Each node at the tree is a multiplication, hence the probability of event C is given as follows:
P(C) = 0.6 x 0.3 + 0.4 x 0.2 = 0.18 + 0.08 = 0.26.
