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)

I’m vary good with science if you need with that

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
