An aircraft has 116 seats.Th airline has found from long experience that on average 2.5%of people who have brought tickets for a flight do not arrive for that flight.The airline sell 120 tickets for a particular flight.Calculate using suitable approximation the probability that more than 116 people arrive for the flight.

Sagot :

Approximately 2 people will not turn up to the flight.
I figured it out by finding 1% (1.16) 
multiplying it by 2 (2.32)
halving 1.16 to find 0.5% (0.58)
And then adding 0.58 to 2.32 to find 2.5% (1.9256)
Round that up to 2 as you cannot have 0.9256 of a person.
Therefore 118 people will arrive for the flight.
Hope I helped
