Answer: D) 1/10
======================================================
Explanation:
Initially there are
- 2 red beans
- 1 yellow bean
- 2 black beans
Giving 2+1+2 = 5 total
The fraction 2/5 represents the probability of picking red
After a red bean is chosen, there's 2-1 = 1 red left out of 5-1 = 4 total. The fraction 1/4 is the probability of getting another red jelly bean.
Multiply those fractions to get the final answer
(2/5)*(1/4) = 2/20 = 1/10
Answer:
2/5
Step-by-step explanation:
There's 5 jellybeans in the bag total and of the five, 2 of them are red, so the probability that Cynthia gives him 2 reds is 2/5.
