Hannah spins a spinner once and then randomly selects a marble from a bag. A representation of the spinner and the bag of marbles is shown below. A spinner with 6 equal sections labeled 1 through 6.
4 blue marbles, 2 red marbles, and 4 green marbles.
She determines that the probability of spinning a multiple of 3 and randomly selecting a blue (B) marble is StartFraction 2 over 15 EndFraction. Which best describes the accuracy of Hannah’s answer?
Hannah’s answer is accurate.
Hannah’s answer is inaccurate. She may have correctly determined the probability of spinning a multiple of 3, but she considered the probability of randomly selecting a blue marble as One-fourth instead of StartFraction 4 over 10 EndFraction.
Hannah’s answer is inaccurate. She may have correctly determined the probability of randomly selecting a blue marble, but she considered the probability of spinning a multiple of 3 as StartFraction 1 over 6 EndFraction instead of StartFraction 2 over 6 EndFraction.
Hannah’s answer is inaccurate. The number of possible outcomes for the events is 60, not 15.
