Answer:
Example:
A bag contains 3 black balls and 5 white balls. Paul picks a ball at random from the bag and replaces it back in the bag. He mixes the balls in the bag and then picks another ball at random from the bag.
a) Construct a probability tree of the problem.
b) Calculate the probability that Paul picks:
i) two black balls
ii) a black ball in his second draw
Solution:
tree diagram
a) Check that the probabilities in the last column add up to 1.
b) i) To find the probability of getting two black balls, first locate the B branch and then follow the second B branch. Since these are independent events we can multiply the probability of each branch.
ii) There are two outcomes where the second ball can be black.
Either (B, B) or (W, B)
From the probability tree diagram, we get:
P(second ball black)
= P(B, B) or P(W, B)
= P(B, B) + P(W, B)
Spencer??
LIKE THE NOVEL "PRETTY LITTLE LIARS"????
OMG I LOVE SPENCER IS ONE OGF MY FAVORITE LOL sorry..
umm well she use this method:
1/3. 4/1
4/3
4
that's it lol .... :v
1.40 as a fraction is a 1 40/100 simplify it. 1 20/50. 1 2/5
HOPE I HELPED!!!
In decimal form it is 8000.00, in word form it is exactly as in the question ten times to the right
