d) Suppose you pick one marble from the bag at random. Find the expected value of its number.

(c) Suppose you pick 9 marbles from the bag at random with replacement. Find the probability that you pick at least one purple marble.

Respuesta :

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:

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