You toss two number cubes. if a sum of 7 or 11 comes up, you get 7 points, if not you lose 2 points. the probabilities for each of the sums is: p(2) = 1/36 p(3) = 1/18 p(4) = 1/12 p(5) = 1/9 p(6) = 5/36 p(7) = 1/6 p(8) = 5/36 p(9) = 1/9 p(10) = 1/12 p(11) = 1/18 p(12) = 1/36 the expected value of the number of points for one roll is: 0 1 3 6

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

the answer is a
