Answer:
The probability that the coin landed heads is 65.3%.
Step-by-step explanation:
Given : Urn A has 5 white and 17 red balls. Urn B has 9 white and 12 red balls. We flip a fair coin. If the outcome is heads, then a ball from urn A is selected, whereas if the outcome is tails, then a ball from urn B is selected. Suppose that a white ball is selected.
To find : What is the probability that the coin landed heads ?
Solution :
Let the event A be the ball taken from Urn A (5 white and 17 red balls)
Let B=A'- the ball taken from urn B(9 white and 12 red balls)
Let W be event that a white ball is selected.
An urn is chosen based on a toss of a fair coin.
P(A) = coin landed on heads =
P(B) = coin landed on tails =
and
Using Bayes formula,
Therefore, the probability that the coin landed heads is 65.3%.
Answer: the only answer is the third one
Step-by-step explanation:
Because 3*5g equals 15g and the only answer choice tha has 15g is the third one because 12g-7g equals 5g and 5g*3 equals 15g
9+(-9)=0 you are showing the opposite sign of the number that added together would give you the sum of zero.
Answer:
By AA similarity
Step-by-step explanation:
In triangle JIK and MJK
angles k=k(Common)
angles JIK = MJK (Both 90 degrees)
in triangles MIJ and MJK
angle m=m common
angles MIJ=MJK
9p=-14
p=-14/9 is the answer to the problem
5p+4p+6= -8
9p= -8-6
9p=-14
p= -14/9
