Answer: D) 1/10

======================================================

Step-by-step 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.
