Of the last 100 customers entering a computer shop, 25 have purchased a computer. If the classical method for computing probability is used, the probability that the next customer will purchase a computer is .75 1.00 .25 .50 ___ The answer is apparently .50 but i am not understanding why that is so, wouldn't it be .25? Or is it that there is a option for the customer to buy or not buy so it makes it 50% so 50/100? I'm not sure...
