D. From a deck of 12 cards, which are numbered 1 to 12, a single card is drawn at random. The number is recorded and then is placed back in the deck. A second card is then drawn at random and recorded. Events are defined as follows: • A: the two cards are composed of one even numbered and one odd numbered card. • B: the first card drawn is even numbered. • C: the sum of the card numbers is even. • D: the sum of the card numbers is 18. i. Are the events A and B independent? Are the events A and B mutually exclusive? ii. Are the events A and C independent? Are the events A and C mutually exclusive? iii. Determine P(D) iv. Determine P(D|C)

To prove that  δabc≅δxyz by hl, we need to have three pieces of information: 1- we need the two triangles  to be right-angled    (this one is given as angle b = angle y = 90 degrees)2- we need to have two corresponding congruent legs    (this one is given as bc = yz = 20)3- we need to have two congruent hypotenuses      (this means that we need to have ac = xz)the third piece of information is the missing one.
