In a middle school of 80 students, 42 girls and 38 boys. What is the probability that if two students were randomly chosen, the first is a boy and then a girl sequentially?

b

step-by-step explanation:

60%

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
