We need to find the probability that a selected animal will be an threatened given they are a bird: P(T/B). So,
Where, Probability of threatened animal that are birds:
=
and probability of bird=
Therefore, P(T/B)= \frac{P(T\cap B)}{P(B)}
=
=
=0.1667
=16.67%

Step-by-step explanation:
In combinatorics, the rule of product states that if there are ways of doing one thing and
ways of doing another thing, then there are
