Determine if they are independent or dependent events
A. There are 3 marbles in a bag, 2 of them are green and of them is red. You draw 2 marbles out of the bag.
B. One person in your class is chosen to lead the green team and then someone is chosen to lead the blue team.
C. P(a)=1/20 P(b)=1/2 P(a|b)=27/50
D. P(not a)=3/4 P(b)=3/10 P(a and b)=3/40
2. Assume that a and b are independent events.
A. P(a)=1/4 P(b)=3/5 P(b|a)=?
B. P(b)=9/20 P(a and b)=9/100 P(a)=?
C. P(a)=7/10 P(a or b)=173/200 P(b)=?
3. Find the missing probabilities
A. P(b)=2/5 P(and b)=1/10 P(a|b)=?
B. P(not a)=3/5 P(a and b)=6/25 P(b|a)=?
C. P(b)=0.45 P(a or b)=0.72 P(b|a)=0.4 P(a)=?
