ASSESSMENT

1. You tossed a five-peso coin five times and you got heads each time. You tossed again and still a head turned up. Do you think the coin is BIASED? Why?

• A. I think the coin is biased because it favoured the heads.

• B. I think the coin is biased because it is expected to turn up tail for the next experiments

• C. I think the coin is not biased because both faces of the coin have equal chances of turning up.

• D. I think the coin is not biased because the probability of turning heads up is 3 4 while that of tails is only 1/4 .

2. A coin is tossed three times. For each toss, the possible outcomes are H (heads) or T (tails). What is the sample space for this experiment?

• A. S= {TTT, TTH, THT, HTT, HTH, HHT, HHH}

• B. S= {TTT, TTH, THT, THH}

• C. S= {HTT, HTH, HHT, HHH}

• D. S= {HHH, HHT, HTH, TTT, TTH, THT}

3. Suppose you toss a fair coin four times, how many possible outcomes are there?

• A. 4

• B. 8

• C. 16

• D. 32

4. How many possible outcomes are there in tossing two fair coins at once?

• A. 1

• B. 2

• C. 4

• D. 8

5. Suppose you are trying to decide what to have for breakfast. You can choose between sopas and a pandesal, and you have four choices for what to drink: coffee, orange juice, chocolate drink, or water. List the sample space.

• A. { Sopas, Pandesal, Water, Coffee, Tea, Orange Juice}

• B. { Sopas & Coffee, Sopas & OJ, Sopas & Chocolate drink, Sopas & Water, Pandesal & Coffee, Pandesal & OJ, Pandesal & Chocolate drink, Pandesal & Water}

• C. { Sopas & Coffee, Sopas & OJ, Pandesal & Chocolate drink, Pandesal & Water}

• D. { Sopas & Pandesal, Sopas & OJ, Sopas & Water, Pandesal & Coffee, Pandesal & OJ, Pandesal & Chocolate drink, Pandesal & Water}
