Sophia has a bag with 3 purple marbles and 4 blue marbles in it. She is going to randomly draw a marble from the bag 280 times, putting the marble back in the each bag after each draw

Sophia will draw a purple marble  Close to 120 times but probably not exactly 120  times

Step-by-step 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
