Answer:
Sophia will draw a purple marble Close to 120 times but probably not exactly 120 times
Explanation:
Sophia has a bag with 3 purple marbles and 4 blue marbles in it
purple marbles = 3
blue marbles = 4
Total marbles = 3 + 4 = 7
Probability of purple marbles = 3/7
probability of Blue Marbles = 4/7
if 280 times , a marble is drawn
then chances of purple marbles = (3/7) 280 = 120
chances of blue marbles = (4/7) 280 = 160
Sophia will draw a purple marble Close to 120 times but probably not exactly 120 times
