SOLUTION:
Case: Conditional probability
P(A/B) is known as conditional probability and it means the probability of event A that depends on another event B. It is also known as "the probability of A given B". P(A/B) Formula is used to find this conditional probability quickly.
Given: Two tests: Math and science and the grades obtained
Required:
P(grade of B | science class)
Method:
P(grade of B | science class).
This interpretes as : Given that a student is selected from the science class, what is the probability that the student got the grade B
[tex]\begin{gathered} P(\text{grade of B | science class)} \\ =\text{ }\frac{n(\text{scienceB)}}{\text{science class}} \\ =\text{ }\frac{8}{25} \\ =\text{ }0.320 \end{gathered}[/tex]
Final answer:
The final answer is 0.320. Option (C)
