Answer:
d
Step-by-step explanation:
P(A) = 0.993 is the probability of event A
_
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1:
_
=> P(A) + P(A) = 1
_
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are:
_
1) P(A) = 0.07
_
2) Yes, A is unlikely because its probability is very low.
