An international flight is scheduled to fly passengers of many different nationalities.

Question

Canadians 17
Costa Ricans 12
Jamaicans 24
Puerto Ricans 8
Mexicans 11
Considering this data, how many of the next 87 passengers to board should you expect to be Jamaicans?
Jamaicans

Answer 1

To calculate the proportion of Jamaican passengers among the total number of passengers, you would add up the number of Jamaicans and divide by the total number of passengers:

24 Jamaicans / (17 Canadians + 12 Costa Ricans + 24 Jamaicans + 8 Puerto Ricans + 11 Mexicans) = 24 / 72 = 0.3333

So, approximately 33.33% of the passengers are Jamaicans. To find out how many Jamaican passengers to expect out of the next 87 passengers, you would multiply the total number of expected passengers by the proportion of Jamaicans:

87 passengers * 0.3333 = 29 Jamaican passengers

Therefore, you should expect approximately 29 Jamaican passengers out of the next 87 passengers to board the flight.
