The probability that a single radar set will detect an enemy plane is 0.9. if we have five radar sets, what is the probability that exactly four sets will detect the plane?
Solution: The given random experiment follows binomial distribution with 
Let x be the number of radar sets that will detect the plane.
We have to find 


Therefore, the probability that exactly four sets will detect the plane is 0.3281
Answer: x > 0
Step-by-step explanation:
First add 4 on each side
5x>0
Then divide by 5
X >0
183.75 because if you did $1470 then divided it by 8 it would =183.75
The answer is 25 because of the Pythagorean theorem. 49+576=625 625 squared=25
