Answer:
0.22
Step-by-step explanation:
defective rate is 7 out of 100
defective rate of 4, or 3, or 2, or 1 defective is:
7/100 + 6/99 + 5/98 + 4/97 ≈ 22/100
The required probability for fewer than 5 defective rate is 0.10
An industrial machine produces widgets, but it has a 0.07 defective rate.
What is the probability?
Probability, can be define as the ratio of favorable events to the n number of total events.
defective rate fewer than 5
p of 4 defective + p for 3 defective+ p for 2 defective + p for 1 defective.
total p = 4/100 + 3/99 + 2/98 + 1/97 ≈ 0.10
Thus, The required probability for fewer than 5 defective rate is 0.10
