Probability Question

#1
I am having trouble with this question I don't really know how to go about it.

Yesterday's production of refrigerator compressors got out of
control for a couple of hours, leaving 10% of the day's production
defective. A sample of 6 was randomly drawn for process control.
What is the approximate chance it would have 2 or more defective?

the answer is 0.11

Thanks again!
