Quizplus · Accepted Answer

To find the expected number of breakdowns per week, we need to calculate the average or mean of the breakdowns per week over the past 30 weeks.

Sum of breakdowns = 88

Expected number of breakdowns per week = Sum of breakdowns / Number of weeks 
= 88 / 30 
≈ 2

Therefore, the best choice is B) 2.
