Probability Quiz

What is a "sample space"?

• The list of all possible outcomes of an experiment

• The most likely outcome of an event

• A set of favorable outcomes

• The probability of a particular event occurring

If a spinner has 5 equally spaced sections numbered 1, 2, 3, 4, and 5, what is the sample space for the experiment of spinning the spinner once?

• {1, 2, 3, 4, 5}

• {1, 2, 3, 4}

• {1, 2, 3}

• {1, 2, 3, 4, 5, 6}

If you flip a coin twice, what is the sample space for this experiment?

• {Heads, Tails}

• {HH, HT, TH, TT}

• {Heads, Heads, Tails, Tails}

• {Heads, Tails, Head-Tail, Tail-Head}

When rolling two dice, what is the sample space for the sum of the two dice?

• {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

• {1, 2, 3, 4, 5, 6}

• {2, 3, 4, 5, 6, 7, 8, 9}

• {2, 4, 6, 8, 10, 12}

What is the definition of an "outcome" in probability?

• A set of possible events that can happen

• The result of a single trial of an experiment

• The number of favorable outcomes

• The total number of possible outcomes
