Two unbiased dice are rolled once. Let A1 be the event "sum of points obtained is an odd number" and A2 the event "one of the faces shown is an ace". Obtain a) P(A1 U A2 ) b) P(A1 ? A2 ) c) P(A1 ? A'2 )

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

there are infinitely many solutions.
