Option 3: 300 phones
Step-by-step explanation:
Given
Phone produces each day: 1000
Number of phones that were checked = 30
Defective phones = 9
So the probability of defective phones will be calculated by dividing the number of defective phones by total number of phones checked.
So, the probability of defective phones
= 9/30
= 0.3 or 30%
So, from 1000 phones the defective phones will be:
1000*0.3
= 300 Phones ..
