A bag contains 3 red marbles, 4 blue marbles and 7 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that both marbles drawn will be red?

Respuesta :

Answer:

0.1428 if you round then it would be 0.143 2/14

Step-by-step explanation:

The probability to the nearest 1000th, that both marbles drawn will be red is 0.0027

Probability-based problem:

What information do we have?

Number of red marbles = 3

Number of blue marbles = 4

Number of green marbles = 7

Total number of marbles = 3 + 4 +7

Total number of marbles = 14

Probability to the nearest 1000th, that both marbles drawn will be red = (3/14) × (2/13) × (1/12)

Probability to the nearest 1000th, that both marbles drawn will be red = 6 / 2,184

Probability to the nearest 1000th, that both marbles drawn will be red = 0.0027
