4 0

<span>If a spinner has 9 equally-sized slices, then there is an equal chance of the spinner landing on any one of those slides. If, as in this case, there are 7 white slices and 2 black slices, then the chance of the spinner landing on a black slice is 2/9. And, to answer the question, the odds of landing on a white slice are therefore 7/9, or about 78%.</span>

If each customer takes 3 minutes to check out, what is the probability that it will take more than 9 minutes for all the custome

AnnyKZ [126]

Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

<h3>What is the discrete probability distribution?</h3>

Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:

P(X = 0) = 0.2;

P(X = 1) = 0.15;

P(X = 2) = 0.30;

P(X = 3) = 0.20;

P(X = 4) = 0.10;

P(X = 5) = 0.05;

Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:

P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.

0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
