Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Volume is length x height x width.

You are given Volume, Length and width, so we multiply the length and width together then divide the volume by that to find the height.

Length x width = 25 * 10 = 250 square cm.

Height = 10,000 cm^3 / 250 cm^2

Height = 40 cm
