POSSIBLE POINTS: 4 A certain star is 2.7 x 102 light years from the Earth. One light year is about 5.9 x 1092 miles. How far
from the earth (in miles) is the star?
The star is
miles from the earth (express your answer in correct
scientific notation. Remember, first factor, a space, lowercase x for multiplication, a space, the base
of 10, the shift 6 (-), and the exponent).

what is the original number? you forgot to add it.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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
