If I calculated it correctly:
17+27 is 44
17+3 and 27+3
20 & 30
20/30 is 2/3
Therefore the answer is:
Ron is 17 and John is 27!
Answer:
1. P(A|B) - option 2
2. does not affect - option 2
3. P(A) - option 1
Step-by-step explanation:
By the definition, the notation P(A|B) reads the probability of event A given that event B has occured. So, for the first gap correct choice is 2 - P(A|B).
If events A and B are independent, then the probability of event B occuring does not affect the probability of event A occuring. So, for the second gap correct choice is 2 - does not affect.
Events A and B are independent, then

Use formula for the conditional probability:

Since events A and B are independent, we get

So, for the third gap correct answer is 1 - P(A)
