Question

You have a bag of gummy worms with 5 green, 3 blue, 6 red, and 2 orange. Which expression represents the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?​

Answer 1

Answer:

$\frac{1}{8}$ I think

Step-by-step explanation:

you have a bag witha a total of 16 gummy worms right? 6 out of 16 of them are red, 5 out of 16 are green.

• so you pull out a red one and eat it. the probabilty of you doing that is $\frac{6}{16}$ . keep it in mind that you ate a gummy worm.
• after enjoying that gummy worm you decide to take another one, but this time, it's green. you know you just ate one right, but you did not replace it now did you? what that means is out of the 16 gummies you had, you are now left with 15 (because you ate one).
• now you are left with 15 gummy worms. you take a green one out of the packet. the probabilty of you doing that is $\frac{5}{15}$.

now that you've got your probabilities all sorted, now it's time to use some basic probability principles. if you ever come across a probability question with the word and, you need to know automatically that you are multiplying. if you ever come across the word or, you are adding. it's always gonna be like this.

so when you multiply your two probabilities, you get the answer $\frac{1}{8}$

whenever you're dealing with probability, make sure you're aware of things that are being taken. check whether they're being replaced or not. the way I attempted at working it out is how the other probability questions involving replacements are solved, no matter what it is.

I really hope you found this helpful (that is if all I said is correct) :)
