Of a quadrilateral abcd the cartesian coordinates of the vertices are known: a (48.61; 41.19) b (16.53; 45.37) c (7.03; 3.57) d (54.98; 5, 16).
from point b the parallel to the da side is drawn, which meets the cd side at point e. obtain the coordinates of point e and the areas into which the quadrilater is divided

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
