In a xy-plane, eight points are given. If a point is selected at random, what is the probability that x+2y>10?

Are u sure that question is complete?

all 8 points could be "above" the line x+2y=10, probability will be 1.
or 7 points above this line and one below it, answer would be 7/8..

Some free advice: start posting entire questions, including answer choices, or people will just ignore your posts.

The question as written is unanswerable.

i apologize for the inconvenience, i posted it to check whether i am missing something coz i thought the problem is incomplete too, but then i thought there might be some concept that i am not aware of...so to confirm that i am not missing any concept i posted the question as it is..
nyways.. i'm sorry, will check this in future.. :oops:
