    A spinner and a fair number cube are used in a game.  The spinner has four equal sections; red, blue, yellow, or green. The faces of the cube are numbered 1 through 6.  What is the probability of a player spinning the color red and rolling a 5 or 6?  (8.11)(A)

    • A. 
    • B. 
    • C. 
    • D. 
    Correct Answer
    B.
    Explanation
    The probability of spinning the color red is 1/4 because there are four equal sections on the spinner. The probability of rolling a 5 or 6 on the number cube is 2/6 because there are two favorable outcomes out of six possible outcomes. To find the probability of both events happening, we multiply the probabilities together: (1/4) * (2/6) = 1/12. Therefore, the probability of a player spinning the color red and rolling a 5 or 6 is 1/12.

    Emily read an article that stated that on average 15% of men are left-handed and 9% of women are left-handed.  Emily gathered her own data by surveying adults at a basketball game.  She found that 5 out of 26 women were left-handed.  What is the approximate difference in percentage between the study's findings and Emily's experimental results?  (8.11)(B)

    • A. 

      4.2%

    • B. 

      6.2%

    • C. 

      10.2%

    • D. 

      19.2%

    Correct Answer
    C. 10.2%
    Explanation
    Based on the information provided, the article stated that 9% of women are left-handed on average. However, Emily's survey found that only 5 out of 26 women were left-handed, which is approximately 19.2%. Therefore, the approximate difference in percentage between the study's findings and Emily's experimental results is 19.2% - 9% = 10.2%.
