A caselet states that in a poll of 400 people, 25% prefer action movies, 35% prefer comedies, and the rest prefer dramas. How many people prefer dramas?
  • Step 1: Understand that the total number of people surveyed is 400.
  • Step 2: Calculate how many people prefer action movies by finding 25% of 400. This is done by multiplying 400 by 0.25, which equals 100.

  • Step 5: Subtract the total number of people who prefer action movies and comedies from the total number of people surveyed. This is 400 - 240 = 160.
