Question

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...

Answer 1

Answer:

0.50

Step-by-step explanation:

The question asks you to apply the classical method of computing probability. In this method, prior events do not interfere in the likelihood of an event happening in the future, instead it states that every possible outcome is equally likely to happen.

In this case there are only two possible outcomes: purchase or not purchase a computer. Therefore, the likelihood that the next customer will purchase a computer is 50% or 0.50.
