A factory is producing bags. The probability that a bag has a fault is 11%. If the factory makes 600 bags in a day, how many are expected to be faulty?

Answer :

Let's find out how many faulty bags we can expect if a factory makes 600 bags in a day and the probability that a bag has a fault is 11%.

1. Identify the total number of bags produced:
The factory produces 600 bags in a day.

2. Identify the probability of a fault:
The probability that any given bag has a fault is 11%, which we can write as a decimal: 0.11.

3. Set up the calculation to find the expected number of faulty bags:
To find the expected number of faulty bags, we multiply the total number of bags by the probability of a fault.

4. Perform the multiplication:
[tex]\[ \text{Expected faulty bags} = 600 \times 0.11 \][/tex]

5. Determine the result:
[tex]\[ \text{Expected faulty bags} = 66.0 \][/tex]

So, we can expect that 66 bags out of the 600 produced in a day will be faulty.
