Answer 1

Answer:

close to 120 times but probably not exactly 120 times

Step-by-step explanation:

Answer 2

Answer:

Sophia will draw a purple marble 120 times .

Step-by-step explanation:

Number of purple marbles in the bag = 3

Number of blue marbles in the bag = 4

Total number of marbles in the bag = 7

$\text{Probability of drawing purple marble from the bag = }\frac{3}{7}$

Each time the marble drawn is put back into the bag.

Also, number of draws = 280

So, Sophia will draw a purple marble = Probability of drawing a purple marble × Number of draws

$\textbf{Hence, Sophia will draw purple marble = }\bf\frac{3}{7}\times 280=120\:\:times$

Therefore, Sophia will draw a purple marble 120 times .
