A probability experiment consists of rolling a six-sided die and spinning the spinner shown at the right. The spinner is equally likely to land on each color. Use a tree diagram to find the probability of the given event. Then tell whether the event can be considered unusual. Event: rolling a 5 and the spinner landing on yellow The probability of the event is 008 (Type an integer or decimal rounded to three decimal places as needed.) Can the event be considered unusual? A. Yes, because the probability is 0.05 or less. B. No, because the probability is 0.10 or less C. Yes, because the probability is greater than 0.10.
