PLZ HELP WILL GIVE BRAINLIEST!!!!!!!!!! AND 20 POINTS!!!!!!!!!!!

A number is randomly selected from {80, 81, 82, 83, 84, 85, 86}.

A is represented by the event that the number picked is less than 84.

What is the probability of the complement of event A?

Because there are 7 numbers in this, and only 4 numbers that are less than 84, the probability would be 4/7 which means there is about a 57% chance of picking a number less than 84.

Hope this helped ! (:

in order to do this see how many numbers u have... in here you have 7 numbers so that will be your denominator. now in order to find the numerator add how many numbers are there less than 84. in this case there are 4 numbers that are less than 84.. this means that there is a 4/7 or 0.57% probability of the complement of event A

Hope this helps
