these marbles are placed in a bag and two
of them are randomly drawn.

what is the probability of drawing two pink
marbles if the first one is placed back in the
bag before the second draw?
give your answer as a ratio, reduced to
simplest terms,
hint: multiply the probability of the 1st event by the
probability of the 2nd event to get your answer,

.

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

answer: sine
