Answer:
Step-by-step explanation:
Given that a particular detection system has a 0.83 probability of detecting a missile attack.
Also each system is independent of the other to detect missile attack.
a) the probability that a single detection system will detect an attack=
b) the probability that at least one of the systems will detect the attack given two systems= 1-Prob no system detects
=
c) If three systems are installed, the probability that at least one of the systems will detect the attack
= 1- none of the three systems detect attack
d) We find that probability of detecting is more if we increase the system form 1 to 2 and 2 to 3.
Hence for safety and defence purpose multiple detection system is recommended.
Answer:
Step-by-step explanation:
Given
The attached triangle
Required
Find y
The attached triangle is isosceles; so:
Also, we have:
--- angles in a triangle
Substitute:
Collect like terms
The number of people who voted follows a binomial distribution with probability of having voted 
and 
subjects, which means the approximating normal distribution should have mean 
and standard deviation 
.
With the continuity correction, you have
