Question 2

MAFS.912.S-IC.1.2:

A student boasts that he is the luckiest person alive because in a jar of marbles, in which there were two blue marbles and eight red marbles, he drew a blue marble out of the jar on four successive tries (after replacing the original). Skeptical, his friend conducts a simulation using a random number table. The digits 0 and 1 represent a success (drawing a blue marble), and the digits 2 through 9 represent not a success (drawing a red marble). Using the first 10 digits in the first row for the first draw and thenext10 digits in thesamerow for the second draw, he records the successes.
