A missile protection system consists of n radar sets operating independently, each with probability 0.9 of detecting a missile e

stepladder [879]

Answer:

A.) The probability that the missile is not detected by any of n sets = (1-0.9)^n = 0.1^n.

Where it's opposite will be that the missile is detected by atleast 1 of the sets. Which will be equals to 1-(0.1)^n.

B.) 0.999= 1-(0.1)^n

Here n=3

For, 0.999999=1-(0.1)^n

n=6.

C.) If n=5

5C4*(0.9)^4*(0.1)^1= 0.32805

r-ruslan [8.4K]

Answer:

l = 15 inches

b=?

perimeter of rectangle = 48 inches

2(l+b) = 48 inches

2(15+b)= 48 inches

28+2b=48

2b=48-28

2b=20

b=20/2

b=10

hence , breadth is 10

this is the answer of your question
