Please see attached, I am having difficulty determining the required calculation based on the question can you help

Need help Clarifying

	Support	Oppose	Neutral	Total
Faculty	250	40	10	300
Students	1000	3500	200	4700
Total	1250	3540	210	5000

• Find the probability that the individual selected opposes the proposed ban

Answer P(E) = 3540/5000=0.708

• Find the probability that the individqual selected is a student.

Answer P(E) = 4700/5000=0.94

• Find the probability that the individual selected is a student and opposes the proposed ban

Answer I believe should be P(E) = 3500/5000=0.7

• Find the probability that the individual selected is faculty or supports the proposed ban

Answer (this is where I begin to question myself?) P(E) = 250/5000=0.05

Or should I have used P(B|A) = 250/300=0.8333? or P(E) 300/5000=0.06 then 1250/5000=0.25 then 0.06+0.25=0.31

Can you help I am getting lost in the wording?
