5 red, 3 yellow, and 2 blue....for a total of 10 marbles
P(first one being blue) = 2/10 which reduces to 1/5
not replaced
P(second one is blue) = 1/9...because u already pick a blue, meaning there is only 1 left, and there is one less marble, so there is a total of 9 marbles.
P(both events happening) = 1/5 * 1/9 = 1/45 <==

Answer:
4. C
5. B
Step-by-step explanation:
4. Circumference = diameter * pi
pi is approximately 3.14
Diameter = 2*radius
Diameter = 2*8 = 16
Circumference = 3.14 (16), so the answer is C.
5. The question asking asking for the surface of the toy box.
Surface area of a cube = 6*the area of one face of the cube = 6 (edge * edge)
Substitute the edge with 2
Surface area of the toy box = 6(2*2) = 6(4) = 24
Surface area is 24 feet squared, so the answer is B
Hope this helps :)
Have an awesome day!!
