Mrs. Brown gives two tests to her class. 30% of the class passed both tests and 45% of the class passed the first test. What
Ad libitum [116K]

Answer:

C) 67%

Step-by-step explanation:

Conditional probability:

P(A given B) = P(A and B) / P(B)

P(passed 2nd given passed 1st) = P(passed 2nd and 1st) / P(passed 1st)

P(passed 2nd given passed 1st) = 0.30 / 0.45

P(passed 2nd given passed 1st) = 0.67

Sati [7]
Hello there, and thank you for posting your question here on brainly.

To find this, you have to find the greatest common factor. (GCF)

GCF = 3

<span>Factor out the GCF: Write the GCF first. Then, in parentheses, divide each term by the GCF.
</span>
3 (15t/3 + 6/3)

Simplify.

-3(5t + 2)

Hope this helped! ☺♥
