Answer:

9 times

Explanation:

If there are 4 pink marbles and 1 purple marble, the probability of picking the purple marble on any individual trial is 1/5 (since there is one purple marble out of a total of five marbles).

Therefore, the best prediction for the number of times you will pick a purple marble in 45 trials would be:

E = (1/5) × 45 = 9

So, the best prediction is that you will pick a purple marble approximately 9 times out of the 45 trials.
