Abird is flying northeast. in the same time it flies 3/5 mile east, it flies 5/6 mile north. how many miles does the bird fly east for every mile it travels north.

9/20 miles

Step-by-step explanation:

we know that

if the bird flies 5/6 miles north for > 3/8 miles east

then

for 1 mile north> X miles east?

X=(3/8)/(5/6)> 18/40> 9/20 miles

the answer is

9/20 miles

85.560%

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
