Answer:
Options 1, 2, 4
Step-by-step explanation:
For option 1. P(both green)
P(one green) = 1/4
P(second green) = 1/4
P(both green) = (1/4)(1/4) = 1/16
For option 2. P(both blue)
P(one blue) = 2/4 = 1/2
P(second blue) = 2/4 = 1/2
P(both blue) = (1/2)(1/2) = 1/4
For option 3. P(first green and then blue)
P(first green) = 1/4
P(second blue) = 2/4 = 1/2
P(first green and then blue) = (1/4)(1/2) = 1/8
For option 4. P(first orange then blue)
P(first orange) = 1/4
P(second blue) = 2/4 = 1/2
P(first orange then blue) = (1/4)(1/2)=1/8
For option 5. P(first orange then green)
P(first orange) = 1/4
P(second green) = 1/4
P(first orange then green) = (1/4)(1/4) = 1/16
Option 1, 2, 4 are correct.
