Answer 2

It's:
1/2 x 1/2 right?

Answer 3

2 dependent events. As I told you before somewhere....

event 1)
tossing tails on a penny (the probability is you already know)

event 2)
prime numbers are
1, 2, 3, 5
(4 out of 6)

Answer 4

1 is usually not considered prime

Answer 5

oh, true

Answer 6

yes, only 2, 3, 5

Answer 7

so (3 out of 6)

Answer 8

and these are independent events, not dependent

Answer 9

Yeah that was what I was thinking about.

Answer 10

yes sorry.
They are not dependent, because the outcome of event 1 doesn't affect outcome of event 2
