Area of each tile: 2.5in * 6in = 15 in^2
Area of the back splash: 2.5 ft * 12 in/ft * 8ft*12in/ft = 2880 in^2
Area of the back splash / area of each tile = 2880in^2 / 15in^2 = 192
Answer: 192 tiles
No I do not agree with (2,-4) I believe the solution is (-4,2)
(A) The probability that you roll a 1 would be 1/6 because there are six sides of a dice and only one is a 1.
(B) The probability that you either roll a 1 or don't roll a 1 is 1/6 and 5/6, since the probability that you do roll a 1 is 1/6 and the probability that you don't is 5/6 since the other 5 sides of the dice are not ones.
(C) As stated above, the probability of not rolling a 1 is 5/6 since there are 6 sides of the dice and 5 are NOT ones.
Hope that helped!
