Question

Red is pun on a spinner with five equal-size sections labeled red,yellow,blue,green, and purple. what is the probability of the complement of the event? Express your answer as a decimal.

Answer 1

Answer: The probability of the complement of spinning red is 4/5 or 0.8 as a decimal.

Explanation:

The complement of an event is the event that it does not occur. In this case, the complement of spinning red would be spinning a color other than red. Since there are five colors on the spinner and they are all equally likely to be spun, the probability of spinning a color other than red is:P(not red) = P(yellow) + P(blue) + P(green) + P(purple)

P(not red) = 4/5Therefore, the probability of the complement of spinning red is 4/5 or 0.8 as a decimal.
