Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
