Answer 4

What does independent mean?

Answer 5

An event that is not affected by previous events.

Answer 6

1. You draw two colored marbles without replacement and get one red and one blue
The fact that you pulled out the red one first means you have to pull out the blue one next. Since there's no replacement, the first event affects the second. This one is NOT independant.

Answer 7

if two coins are tossed what is the probability that the firt coin will show heads and the second coin will show tails

1/2
1/4
1/8
1/16

Answer 8

thanks

Answer 9

2. You pull a green tile from a bag of tiles return it and the pull a yellow tile.
Since you RETURN it, and place the green tile back, you're putting everything back into the original state again. What you did before doesn't affect what is to come. So this one is

INDEPENDANT.

Answer 10

can u help me with one more ?

Answer 11

3. you toss two coins and get one head and one tail
Independant. It doesn't matter if you got heads or tails before, the chance of getting heads or tails will always be 50-50

Answer 12

1/2 ?

Answer 13

4. you choose two different ice cream flavors for a cone
I would say that your second choice would be dependant on your first (i.e. if you chose vanilla for your first scope, you'd want something different for the next). This is NOT independant.

Answer 14

if two coins are tossed what is the probability that the firt coin will show heads and the second coin will show tails

1/2
1/4
1/8
1/16


Yes. You are occrect. It is 1/2.

Remember my explantation before? They are independant of each other. So it will ALWAYS be 50-50, no matter what the other coin showed.

Answer 15

It's actually 1/4.

Easiest way to explain is to count all possible events:

1) 1-st heads, 2-nd heads;
2) 1-st heads, 2-nd tails;
3) 1-st tails, 2-nd heads;
4) 1-st tails, 2-nd tails.

You need only one event - 1-st heads, 2-nd tails. So the probability of the event is 1/4.
