The correct statement is that the probability is B. Event F for female and event D for drama are independent events.
<h3>What are independent events?</h3>
It should be noted that two events are independent when the occurence of one doesn't affect the probability of another one occuring.
The probability of females will be:
= 3/5 = 0.6
The probability of drama will be:
= 40/240 = 0.167
In this case, they're both independent.

Answer: Santa's speed in still air is 6 miles per minute
Speed of the wind is 1 mile per minute
Step-by-step explanation:
Let x represent the speed of Santa in still air. It is assumed that in still air. She is flying with the wind. If the speed of the wind is y, then him total speed is x + y
It takes Santa 5 minutes to fly 35 miles with the wind.
Speed = distance / time
It means that
x + y = 35/5 = 7
It takes him 7 minutes to fly 35 miles against the wind. This means that his total speed will be x - y
Speed = distance/time. Therefore,
x - y = 35 /5 = 5 - - - - - - 1
Substituting x = 7 - y into equation 1, it becomes
7 - y - y = 5
-2y = 5 - 7 = -2
y = -2/-2 = 1
x = 7 - y = 7 - 1
x = 6
