Question

are the two events dependent or independent? Explain. 1. you pick one of 7 names from a hat and then pick a second name without replacing the first one. 2. you spin a spinner with 5 equal sections and pick a marble froma bag containing 2 green marbles and 4 blue marbles.

Answer 1

1. you pick one of 7 names from a hat and then pick a second name without replacing the first one.


Since you're not replacing the names, the second probability will change based on the first. So the two events are dependent

Answer 2

2. you spin a spinner with 5 equal sections and pick a marble froma bag containing 2 green marbles and 4 blue marbles.

these two events are independent because neither event alters the probability of the other event
