One bag contains three white marbles and five black marbles, and a second bag contains four white marbles and six black marbles. a person draws one marble from each bag. find the probability that both marbles are of the same color?

Probability of both the marbles be of same color is 21/40.

Step-by-step explanation:

One bag contains 3 white marbles and 5 black marbles.

Second bag contains 4 white and 6 black marbles.

A person draws one marble from each bag and we have to find the probability that both the marbles are of same color.

Probability of getting both balls white = P(ww) = (3/8)×(4/10) = 3/20

Probability of getting both the balls black = P(bb) = (5/8)×(6/10) = 15/40

Probability of getting either both the balls black or white = 3/20 + 15/40 = 21/40

Therefore the probability of getting both the marbles of same color = 21/40

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
