Matching suits A standard deck of playing cards consists of 52 cards with 13 cards in each of four suits: spades, diamonds, clubs, and hearts. Suppose you shuffle the deck thoroughly and deal 5 cards face-up onto a table.
a. What is the probability of dealing five spades in a row?
b. Find the probability that all 5 cards on the table have the same suit.
Suppose this player attempts shots in a game and makes only of them. Does this provide convincing evidence that she is less than a shooter?
a. Yes, because () is less than
b. Yes, because she never made of her shots in the simulation.
c. No, because it is plausible (believable) that she would make or fewer shots by chance alone.
d. No, because the simulation was only repeated times.
e. No, because more than half of the simulated results were less than
Middle school values Researchers carried out a survey of fourth-, fifth-, and sixth-grade students in Michigan. Students were asked whether good grades, athletic ability, or being popular was most important to them. The two-way table summarizes the survey data. 
Suppose we select one of these students at random. What’s the probability of each of the following?
a. The student is a sixth-grader or rated good grades as important.
b. The student is not a sixth-grader and did not rate good grades as important.
Another commercial If Aaron tunes into his favorite radio station at a
randomly selected time, there is a probability that a commercial will be playing.
a. Interpret this probability as a long-run relative frequency.
b. If Aaron tunes into this station at randomly selected times, will there be exactly one
time when a commercial is playing? Explain your answer.
Is this your card? A standard deck of playing cards (with jokers removed) consists of cards in four suits—clubs, diamonds, hearts, and spades. Each suit has cards, with denominations ace, jack, queen, and king. The jacks, queens, and kings are referred to as “face cards.” Imagine that we shuffle the deck thoroughly and deal one card. Define events : getting a face card and : getting a heart. The two-way table summarizes the sample space for this chance process
