a) The probability that both John and Jane watch the show is 0.12.
b.The probability that Jane watches the show, given that John does is 0.1714.
c)They do watch show independent of each other.
Step-by-step explanation:
Here, as given in the question:
Probability that John watches a certain show = 0.7 ⇒ P(J) = 0.7
Probability that Jane watches a certain show = 0.3 ⇒ P(Je) = 0.3
Probability that John watches a certain show given Jane watches it to
= 0.4 ⇒ P(J/Je) = 0.4
a. ) Here, we need to find the probability of both Jane and John watching a show , P(J∩Je)
Now, by BAYES THEOREM:
Hence the probability that both John and Jane watch the show is 0.12.
b.) The probability that Jane watches the show, given that John does is P(J/Je)
By BAYES Theorem:
Hence, the probability that Jane watches the show, given that John does is 0.1714.
c) As we can see P(Jane ∩ John) = 0.12
So, the probability of both of them seeing the show TOGETHER is 0.12.
Hence, they do watch show independent of each other and the probability of doing that is 1.0.12 = 0.88
For this case we give as data the following equation:
Where "x" represents the cost of a ticket.
By clearing the value of "x" of the equation we can know the cost of a ticket.
If we subtract 12 from both sides of the equation, we have:
If we divide between 4 on both sides of the equation:
Therefore, the cost of a ticket is $ 9.00
Answer:
Option C
Answer:
Step-by-step explanation:
From the diagram, side length is opposite to angle A and side length
is adjacent to angle A.
Recall the mnemonics SOH CAH TOA.
We use TOA, because it involves opposite and adjacent.
The correct choice is A.
