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^2)-4
Step-by-step explanation:
expand using the distributive property of multiplication
Answer:
A full circle is 360 degrees so 2/3 is 120
