The "explanation" for the problem has a typo in it. There are 11 possible ice cream/yogurt flavors to choose from, regardless of whether any are low-fat, so the total number of ways of choosing any 2 from the selection is
In particular we want to count the number of ways of picking 1 ice cream and 1 yogurt flavor from the low-fat variety. There are 6 total choices that are not low-fat of which we choose 0, 3 choices of low-fat ice cream of which we choose 1, and 2 choices of low-fat yogurt of which we also choose 1. In terms of the binomial coefficient, this is
So the probability of getting such a combination is
.

OK. I'll try. There's not too many points at risk here.
3/5 =y y=1/15 I don't understand what this means.
If 3/5 = y then y = 3/5 .
1/2 p = (1-3/10)
1/2 p = 1.3 Multiply each side by 2. p = 2.6 .
6w = 13.5 Divide each side by 6. w = 2.25
4.2 q = 44.1 Divide each side by 4.2 . q = 10.5 yay!
4/7 b = 5/8 Multiply each side by 7. 4 b = 35/8
Then divide each side by 4. b = 35/32 or 1 and 3/32
or 1.09375
1-1/3 b = 8
4/3 b = 8 Multiply each side by 3 . 4 b = 24
Then divide each side by 4 . b = 6
Answer:
I have no idea :D
Step-by-step explanation:
Answer:
30% of people surveyed were satisfied with the car.
Step-by-step explanation:
We are given:
Total participants in survey= 2800
People satisfied with car = 840
We need to find percent of the people surveyed were satisfied with the car.
The formula used is:
So, 30% of people surveyed were satisfied with the car.
