1833 bomber planes go out on a mission over enemy territory. 1002 of them come back. A statistician is asked to analyze the damage on these planes in order to determine which areas of the plane need better armor. To do so, the 1002 planes are each assigned a number from 1 to 1002. Then, 100 numbers between 1 and 1002 are randomly selected, and the corresponding planes are investigated for damage. It is found that 73% of the planes have significant damage to a particular section. What is the margin of error?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b
