Question
A bag contains blue and pink raffle tickets. What is the complement of selecting a blue raffle ticket if the probability of selecting a pink raffle ticket is 0.23?
Solution
The complement of an event is the probability that the event does not occur. In this case, the event is selecting a blue raffle ticket. The complement of this event would be not selecting a blue raffle ticket, which means selecting a pink raffle ticket.
The probability of an event and its complement always add up to 1. So, if the probability of selecting a pink raffle ticket is 0.23, then the probability of not selecting a pink raffle ticket (which is the same as the probability of selecting a blue raffle ticket) is 1 - 0.23 = 0.77.
So, the complement of selecting a blue raffle ticket is 0.77.
