from a jar of red jellybeans and white jellybeans, the probability of picking a white jellybeans is 2/3. if the jar contains 24 jellybeans, how amny red jellyeans are in the jar
1 6
2 8
3 12
4 16
plz help i have no idea about this
2/3 * 24 = 16
So there are 16 white candies in the jar.
How many red ones are there?
is it 24-16=8
Right.
thanks
What is the temperature when water freezes?
I have one more question
What is the temperature when it steams?
Water freezes at 0 degrees Centigrade which is 32 degrees Fahrenheit. It boils at 100 degrees C and 212 degrees F.
To find out how many red jellybeans are in the jar, we'll use the information given about the probability of picking a white jellybean.
Let's assume the number of red jellybeans in the jar is "x". Since we have a total of 24 jellybeans, the number of white jellybeans would be (24 - x) (this is because the total number of jellybeans minus the number of red jellybeans will give us the number of white jellybeans).
The probability of picking a white jellybean is given as 2/3. Probability is calculated by dividing the desired outcomes by the total possible outcomes. In this case, the desired outcome is picking a white jellybean, and the total possible outcomes are all 24 jellybeans.
So, we can set up the equation:
(desired outcomes / total outcomes) = 2/3
The desired outcome is picking a white jellybean, which is (24 - x), and the total outcome is 24. Therefore, we have:
(24 - x) / 24 = 2/3
To solve this equation, we can start by cross-multiplying:
3(24 - x) = 2 * 24
72 - 3x = 48
Now, let's isolate the variable by subtracting 72 from both sides:
-3x = 48 - 72
-3x = -24
Finally, divide both sides by -3:
x = (-24) / (-3)
x = 8
So, there are 8 red jellybeans in the jar.
Therefore, the answer to your question is option 2: 8.
