Option a, 0.10
Step-by-step explanation:
Given that of the last 500 customers entering a supermarket, 50 have purchased a wireless phone.
i.e. out of 500 customers 50 customers purchased
Hence probability for any random customer to purchase =![\frac{50}{500} =0.10](/tpl/images/0397/0126/c4528.png)
Thus we find that if the relative frequency approach for assigning probabilities is used, the probability that the next customer will purchase a wireless phone is
Option a)
0.10
This is based on the assumption that the past pattern of purchase determines the probabiltiy
