Answer 2

Explanation:

Probabilities greater than 1/5

1 ) choosing 1 red marble = 3 / 10 which is greater than 1 / 5 .

2 ) choosing 1 white marble, replacing it, and choosing another white marble

choosing 1 white marble = 5/ 10 = 1 / 2

choosing white marble next time = 1 / 2

choosing 1 white marble, replacing it, and choosing another white marble

1 / 2 x 1/2 = 1/4 which is more than 1/5

3 ) choosing 1 white marble 5 / 10

= 1 /2 which is more than 1 / 5 .
