What is the probability of picking an ace or picture card from a deck of cards?
If you pick 37 cards without replacement, or pick a card from the bottom of a mint deck, the probability is 1: it is a certainty. If you pick a random card from a deck, then the probability is 4/13.
In each case are the two events dependent or independent Toss a dime and then toss a quarter. Pick a card from a deck of cards. Keep the card and pick another.?
Picking cards without replacing them are NOT independent events, since once you pick a card, you can't pick the same card again.

What is the probability of getting two adjacent numbers out of 80?
If two people pick a number from 1 to 80, then there are 79 possible adjacent pairs that these numbers could go in. For each of these pairs, there are two options (one with person a picking the lower number and one with person b picking the lower number). Thus there are 158 possible pairs. The chance that person 1 will pick any given number is 1/80. The chance that person two will pick any given number is 1/80. Thus the probability that they have picked adjacent number is (1/80)2x158 = 0.0246875
How many jeans should a guy have?
I personally think jeans are more important than shirts because shirts are easy to pick out and buy. Although jeans I believe, need to look as good as possible and attractive to people. When I go to a store I buy more jeans than shirts. So I would say don't spend your whole bank account on jeans but try buying more jeans than shirts but don't get to crazy and only buy just jeans because you need to have shirts to go with them sometimes. When I go to a store I buy anywhere from 3-5 jeans. Maybe that should help.
