Vaselesa [24]

C) The probability that you pick at least one purple marble is 98%.

<h3><u>Probability</u></h3>

The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.

Now, to answer the questions, the following calculations must be done:

  • 100 - 2 = X
  • 98 = X
