Step-by-step explanation:
I took the test aswell.
Total number of bulbs produced=5000
total number of samples=120
number of defective=3
Probability that a bulb selected at random is defective will be:
3/120=0.025
The total number of bulbs that could be defective out of 5000 bulbs produced will be:
5000(0.025)=125 bulbs
Answer: b. It's a fair method because each result is an equally likely possible outcome.
The number of students is same as the number of the sides of the dice. In this scenario, the school principal will roll two dices three times and the number that repeated most will be chosen. For every dice, all number will have equally likely possibility so the randomization is fair(1/6 chance for every student).Rolling the dice >1 times will have a problem because there is a high chance to get draw result. It doesn't have any correlation with fairness though.
