Using conditional probability, it is found that there is a 0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.
<h3>What is Conditional Probability?</h3>
- <em>Conditional probability</em> is the <u>probability of one event happening, considering a previous event</u>. The formula is:

In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: Patient has Medicare.
- Event B: Patient has Medicaid.
For the probabilities, we have that:
- 35% of the patients have Medicare, hence
.
- Of those who have Medicare, there is a 10% chance they also have Medicaid, hence
.
Then, applying the <em>conditional </em>probability:




0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.

The answer is the second option-always
Answer:
A)
f(t) = 50 * 1.2^t
B)
f(3) = 50 * 1.2^3 = 86.4 tree frogs
C)
f(t) = 50 * 1.2^t = 200 --> t = LN(200/50)/LN(1.2) = 7.604 years
D)
f(-1) = 50 * 1.2^(-1) = 41.67 tree frogs
