Answer:
D
Step-by-step explanation:
Let A and B be two events as shown in the picture.
We have to say which one we want, and use the symbol "|" to mean "given":
Notion B|A means "Event B given Event A"
In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B?"
P(B|A) is also called the "Conditional Probability" of B given A.
In your case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".
