Answer:
C 1/2
Step-by-step explanation:
There are 4 suits, 2 suits are red (hearts and diamonds) while 2 are black (clubs and spades)
Since 13 cards are in each suit, 26 cards are red ( 2 * 13)
There are 52 total cards
P (red) = red cards/ total cards
= 26 / 52
= 1/2
z = -9.538546756+ 15.26486573i
z = |z| cos theta + |z| i sin theta
We know |z| and theta
z = 18 cos 122 +18i sin 122
i d k
is simply the difference of both numbers of course, the price it was sold minus the price it was bought at.
