A bag contains 2 red marbles, 8 blue marbles and 3 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:

0.012

Step-by-step explanation:

The chance of pulling a red marble the first time is 2/13.

The chance of pulling a red marble the second time is 1/12.

Since the events are independent, you can multiply the two probabilities together:

2/13 x 1/12

= 1/78

= 0.012
