There are 12 cards with different letters & patterns. The probability of randomly choosing [random card] is #[random card]/total cards.
Think of that as ratio as a %chance or probability of written as P(X). The question says to write the %chance as a fraction.
1) 2/12 = 1/6
2) 2/12 = 1/6
3) 0/12 = 0
4) 12/12 = 1
5) This is tricky. M & T would imply one card with both letters on it. 0/12 = 0
6) 4/12 = 1/3
7) 6/12 = 1/2
8) 5/12
9) 3/12 = 1/4
10) 8/12 = 2/3
11) 10/12 = 5/6
12) Odds = [favorable]:[unfavorable] = 5:7
Answer:
95 cents per Muffin
Step-by-step explanation:
Set up the long division.
8 | 7 6 0
2. Calculate 76 ÷ 8, which is 9 with a remainder of 4.
9
8 | 7 6 0
7 2
4
3. Bring down 0, so that 40 is large enough to be divided by 8.
9
8 | 7 6 0
7 2
4 0
4. Calculate 40 ÷ 8, which is 5.
9 5
8 | 7 6 0
7 2
4 0
4 0
5. Therefore, 760 ÷ 8 = 95.
Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
