Answer:
C. Independent, 49/1296
Step-by-step explanation:
A jar contains 12 red balls, 7 green balls, 10 white balls, and 7 yellow balls.
Total balls = 12+7+10+7
Total balls= 36
Two balls are chosen at random with replacement.
The probability that the both balls are green = probability of the first ball to he green * probability of the second ball to be green
The probability that the both balls are green= 7/36 * 7/36
The probability that the both balls are green= 49/1296
The probability that the both balls are green= 49/1296
