Question

Please answer this !!

Jackson has a bag that contains 5 blue socks, 7 pink socks, and 8 yellow socks.

Jackson removes a single sock from the bag 50 times. Each time he records the color of the sock that is drawn. He replaces the socks into the bag before the next draw.
How many blue socks would be expected to be drawn if 1000 pulls are conducted? 10,000 pulls?​

Answer 1

for 50 pulls, 12.5 blue socks, but you cant have half of a sock so we say 12

for 1000 pulls, 250 blue socks

for 10,000 pulls, 2500 blue socks

Explanation:

First we add 5, 7 and 8 to find the total number of socks, 5+7=12 and 12+8 = 20

5 is the amount of blue socks, so

5/20 * how many pulls are conducted is the probability for blue socks

7 is the amount of pink socks, so

7/20 * how many pulls are conducted is the probability for pink socks

and

8 is the amount of yellow socks, so

8/20 * how many pulls are conducted is the probability for yellow socks
