# :URGENT: Kindly solve this question asap please! watch

1. Two dice rolled once, the probability of obtaining same faces is:
i) 1/6
ii) 0
iii) 5/6
vi) 1/2
v) 1/3
2. so if you draw a 6 x 6 grid you can tick the relevant boxes where the scores are the same. then work out the probability as a fraction out of 36.

Yeah, youre right but considering the fact that this is an MCQ and should take a minute or so to solve, the grid method is gonna take too long. Any shorter method?

Well, two dice have 12 sides in total, and 2 faces will land the same number. so that's 2/12, making it 1/6 if you simplify it by dividing it by 2.

Yes, though you need to be comfortable with probability.

The two rolls are independent events. This means that for the event "Face X on both" we take the probability of "face X on die 1" and multiply it by the probability of "face X on die 2". Clearly, X=1,2,3,4,5,6 and for each X the probability is . Since there are 6 possibilities for X, we just multiply 1/36 by 6

The poster is not askingyou to do a grid method - there are 36 possible outcomes - how many give a double?
