Michelle is deciding where to eat for dinner today. There are 4 choices: Mexican, Italian, Japanese and Korean. These choices are written down on paper and mixed in a bag. There are twice as many papers of Mexican than papers of Japanese. If she takes one piece of paper out of the bag without looking:

  • The probability that it is Mexican is 0.3
  • The probability that it is Italian is 0.2

What is the probability that Michelle picks Korean?
