Question 1185152: The cadet engineers of a service company consists of 60% electrical engineers and 40% civil engineers. A random sample of 8 engineers is selected. What is the probability that among the engineers in the sample at least 7 are electrical engineers? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! What is the probability that all 8 are EE? That is 0.6^8=0.0168
The probability that 7 are EE is 8*0.6^7*0.4^1=0.0896
That sum is 0.1064
