The answer is 12:1
note: this is often read as "12 to 1"
==============================================
Explanation
We have exactly four card that are labeled "3" and 52 cards total. So there are 52-4 = 48 cards that are not labeled "3".
From here you write the ratio 48:4 to indicate the odds against drawing a 3. There are 48 ways to lose, 4 ways to win. You list the number of ways to lose first when it comes to "odds against" type of problems.
Next step is to reduce the ratio 48:4 to get 12:1, note how I divided both parts by the GCF 4
48/4 = 12
4/4 = 1
So thats how 48:4 reduces to 12:1
If you focus on one suit, say the spades, then we have 12 cards that arent a 3 of spades while exactly one card is a 3 of spades. This is one way to see why 12:1 is the answer. If you were saying this out loud to a friend, then you might say something like "the odds against drawing a three are 12 to 1".
Answer:
7.56
Step-by-step explanation:
14x.50(the remainder after you subtract the percent from 100) = 7
8% of 7 is 0.56
7+0.56=7.56
Equation for one year:
0.0725(400)
But we have 7 years:
7(0.0725(400))
Multiply in the parentheses
7(29) = 203
400 + 203 = 603
You now have $603, and made $203
