Expected number of manufacturing breakdowns

Reference no: EM1390544

1. ABC Manufacturing has six machines that perform particular task. Breakdowns happens frequently for this machine. Past records indicate that the number of breakdowns that happen each day is described by the probability distribution seen below:

a) What is the expected number of breakdowns in any given day?

b) What is the variance for this distribution?

c) What is the probability that there will be at least 2 breakdowns in a day?

Number of Breakdowns----Probability

0 0.4

1 0.3

2 0.2

3 0.1

More than 3 0.0

2. Summarize the steps of the quantitative analysis approach.
