Answer:
38% probability that a randomly selected student is female or a physics major.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
Physics majors or female
10 physics majors(of which 3 are female).
12 female(the 3 female physics majors have already been counted, so we count 9)

Total outcomes:
50 students, so 
Probability

38% probability that a randomly selected student is female or a physics major.
Hey there!
First, we'll solve for x = 0.
The first step is to replace x with 0 anytime it appears in the equation.
f(0) = 7(0) + 2
Multiply 7 by 0 next because multiplication comes before addition in PEMDAS.
f(0) = 0 + 2
Then, add 2 to 0 since it is the last step.
f(0) = 2 The value of f(x) when x = 0 is 2.
Now we can solve for x = 1.
The first step is to replace x with 1 anytime it appears in the equation.
f(1) = 7(1) + 2
Multiply 7 by 1 next because multiplication comes before addition in PEMDAS.
f(1) = 7 + 2
Then, add 2 to 7 because it is the last step.
f(1) = 9 The value of f(x) when x = 1 is 9.
Hope this helps!
