Probability of at least 8 sqm to be used = 0.8
Step-by-step explanation:
Given: The quality assurance team has found that there is mean of 4 major defects in one square meter of fabric .The Company’s QA process rejects the fabric if the number of defects exceeds 5. Spenser has sent a bulk of ten square meters.
Find: Probability that at least eight square meters can be used for production.
Solution:
Mean of defects = 4 / sq. m
Total meters = 10 sq.m
QA = more than 5 / sq. m
The mean of defects is at 4 per square meter, so it is in acceptable limits.
Probability of at least 8 sqm to be used = 8 / 10 = 0.8
