Answer:
Using Pythagorean theorem:
x = sqrt( 15^2 + 36^2) = 39
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%

Answer: D=22
Step-by-step explanation:
this is because if multiply f by r you get D and then you do all the other rmathematics and you wind up with 22
Answer:
probability that at least one dies shows a 5.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Each dice:
6 sides, one of which is 5.
So 6-1/6 = 5/6 probability of rolling a 5.
Probability of not rolling a five in two rolls:
(5/6)^2 = 25/36
Probability of rolling a five in at least one of the rolls:
probability that at least one dies shows a 5.
