Answer :
10 red
8 blue
2 green
Total number = 20
Probability that Gina takes a red pen = number of red pens divided by the total = 10/20 = 0.5 = 50%
If she repeats the event, the second time the probability is the same: 0.5 = 50%
Probability of two events = probability of the first one multiplied by the probability of the second = 0.5 x 0.5 =0.25 = 25%
Answer:
Probability = 0.25 = 25%
