Evelyn has a bag containing red (R), blue (B), and green (G) marbles as shown below. If each marble is replaced after it is drawn, what is the probability of randomly drawing three consecutive red (R) marbles

Respuesta :

Answer:

the probability of drawing three consecutive red marbles is based on how many red marbles you have and many marble there is in total.

Answer:

27/512

Step-by-step explanation:

P(3 consecutive red)=P(red)×P(red)*P(red)=3/8*3/8*3/8=27/512.

The reason P(red)=3/8 for each picking of marble us because you are putting the marble back in and there are 3 red while you have 8 marbles in all.
