PEMDAS. First, use the distributive property with -3(2x) + -3(-4) to get -6x + 12. Remember the 9, so you get 9 - 6x + 12. Now add 9 and 12 to get 21 - 6x.
QUESTION A
The probability of an event is calculated using the formula:
There are 4 nines in a standard deck of cards. Therefore, there are 48 cards that are not nines.
Since there are 52 cards, the probability is calculated to be:
The probability is 12/13.
QUESTION B
Odds in favor of a particular event are given by the number of favorable outcomes to the number of unfavorable outcomes. The formula is written out to be:
Since we have that the number of favorable outcomes is 48 and the number of unfavorable outcomes is 4, we have that the odds in favor are given to be:
The odds are 12 to 1.
3%?? The question doesn't make much sense.
