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)
Assuming Lindsey takes 5 hours to mow a lawn, she earns from twelve lawns
12*70=$840.
If the above assumption is not correct, @funnyork2005 needs to clarify the question.
Answer:
A. y = 9√3
Step-by-step explanation:
The relationship of the sides of the triangles are as follows:
First leg = x
Second leg = x√3
Hypotenuse = 2x
Since we know the first leg is 9, multiply that by √3.
Therefore, y = 9√3.
Answer:
FOR red one = 1/26
FOR black three = 1/26
FOR six of hearts = 1/52
Step-by-step explanation:
TECHNICALLY EVERY CARD WOULD BE 1/52 BUT SINCE THERE R TWO DIFFERENT TYPES OF BLACKS AND REDS THE FIRST TWO ARE 1/26
