This picture is too blurry for me to see the actual problem, but it looks like subtracting fractions, you just subtract the numerator (top number) from the other numbers' numerator, and the denominator stays the same, example:
6/8-2/8=4/8
If your teacher wants it in simplest form you just duvide the numerator and denominator by he same number, example
4/8 divided by 4/4=1/2
Answer: Our required probability is 0.11.
Step-by-step explanation:
Since we have given that
Number of workers in first shift = 21
Number of workers in second shift = 15
Number of workers in third shift = 13
We need to find the probability of choosing exactly two second shift workers and two third shift workers.
So, it becomes,
Hence, our required probability is 0.11.
