Answer: 82%

To find the probability that a stamp chosen at random from Macie's collection is from Belgium, we need to divide the number of stamps from Belgium by the total number of stamps in her collection.

Probability = Number of stamps from Belgium / Total number of stamps

Probability = 41 / 50

To convert this fraction to a percentage, we can multiply it by 100:

Probability as a percentage = (41 / 50) x 100% = 82%

So, the probability that a stamp chosen at random from Macie's collection is from Belgium is 82%.

why do we need to do this? we need to divide the number of stamps from Belgium by the total number of stamps in her collection.

We need to do this because probability is a way to measure the likelihood of an event occurring. In this case, the event is selecting a stamp from Belgium out of Macie's collection, and the probability is the number of stamps from Belgium divided by the total number of stamps in her collection. By dividing the number of stamps from Belgium by the total number of stamps, we get the proportion of stamps in her collection that are from Belgium, which is a way to measure the likelihood of selecting a stamp from Belgium. Expressing this proportion as a percentage gives us a more intuitive understanding of the probability.
