 May 15, 2011 MATH - PROBABILITY by: Staff The question: THERE ARE 10 BULLDOGS, 23 COLLIES, 20 TERRIES, 31 HUSKIES, AND 34 OTHER TYPES OF DOGS.. ESTIMATE THE PROBABILITY THAT THE NEXT DOG APPLICATION WILL BE A BULLDOG? The answer: P(E) = (number of times an specific event is observed) ÷ (total number of events observed) Number of times an specific event is observed = number of Bulldogs = 10 Total number of events observed = the total of number of dogs = 10+23+20+31+34 = 118 P(E) = (10) ÷ (118) P(E) = (5) ÷ (59) P(E) = 5/59 To convert this number to a percent, multiply by 100 P(E) = (5/59)*100 P(E) = (500/59) P(E) = 500/59 P(E) = 8.47% The final answer: the probability that the next dog application will be a bulldog is 5/59 (this is a probability of 8.47%) Thanks for writing.
