We need to find the probability that a selected animal will be an threatened given they are a bird: P(T/B). So,

$P(T/B)= (P(T\cap B))/(P(B))$

Where, Probability of threatened animal that are birds:

$P(T \cap B)$ =
(15)/(475)

and probability of bird=
(90)/(475)

Therefore, P(T/B)= \frac{P(T\cap B)}{P(B)}

=
((15)/(475))/((90)/(475))

=
(15)/(90)

=0.1667

=16.67%
