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:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = 
r³
Plug in the volume and solve for r, the radius:
V = 
r³
7961 = 
r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
ANSWER: 5 minutes 20 seconds
WORK: entire train to get out of tunnel - 2900+300 = 3200 meters till it's out
at 600 meters per minute ...3200/600 = 5 1/3 = 1/3 of a minutes is 20 seconds
