What are the coordinates of a’ in quadrilateral a’b’c’d’

cordanite a is (-1,2)

The coordinates of A is (-1, 2)

You just first move over to the left on the X axis making your x coordinate a negative. So when you you get to -1 you go up to where A is, which is at positive 2. Your y coordinate is positive because you're moving up on the Y axis and not down.

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
