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

Probability

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:

  • B) 2/10 x 1/9 = X
  • 0.2 x 0.11111 = X
  • 0.022222 = X
  • X x 100 = 2.22

  • C) 100 - (2/9x9) = X
  • 100 - 2 = X
  • 98 = X
