Consider the experiment where you select one card at a time, at random and without replacement, from a playing 52-card deck (13 cards per suit). Let R, be the event that a red card is the ith draw from the deck. Answer the following questions: 1. Find a set of events (other than card color) that partitions the sample space for this experiment. Be clear in naming these events. 2.

Problem 3
Consider the experiment where you select one card at a time, at random and without replacement, from a playing 52-card deck (13 cards per suit).
Let R; be the event that a red card is the ith draw from the deck.
Answer the following questions:
1. Find a set of events (other than card color) that partitions the sample space for this experiment. Be clear in naming these events.
2. Using the sample space partitions you found in (1) and the Law of Total Probability to compute P(R1).
3. Compute P(R2).
Problem 4
The probability for a disease X is 0.01.
• if a person has the disease, the test results are positive with probability 0.90, and
• if the person does not have the disease, the test results are negative with probability 0.80.
Which of the following statements is true? Show your work.
1. The test results are positive with probability 0.2 when a person does not have the disease (false positives).
2. When a person has the disease, the test results are negative (false negatives) with probability 0.2.
