Answer:
2/75
Step-by-step explanation:
6 of the 30 pens are green, so the probability of selecting a green pen is 6/30 = 1/5.
The pen is then replaced, so there are still 30 pens in the drawer. 4 of the pens are black, so the probability of selecting a black pen is 4/30 = 2/15.
The probability of both events is therefore 1/5 × 2/15 = 2/75.

Answer:
60%
Step-by-step explanation:
let ,x% is birds of prey
total animals=110
birds of prey=66
then,
x%of 110=66
x/100×110=66
110x/100=66
1.1x=66
x=66/1.1
x=60%
I'm not sure if this is correct.
