The probability that all seven arrows will not hit the bullseye is 1 2/5
Probability calculate how likely it is for an event to occur. The chances of an event occurring is between 0 and 1. The value of the event is one if the event happens and zero if the event does not happen.
For example the probability that it would rain everyday of the week lies between 0 and 1. If it rains, a value of 1 would be attached to the event and if it does not rain all the days of the week a value of zero would be attached to the event.
Probability all seven arrows does not hit the bullseye = number of arrows x probability of one arrow not hitting the bullseye
Probability that one arrow does not hit the bullseye = 1 - 4/5
5/5 - 4/5 = 1/5
Probability = 1/5 x 7 = 7/5 = 1 2/5
