Margie runs a simulation of 100 trials. In
the simulation, she used a random
number generator to select 7 digits
from 1 to 3 with 1 representing a pack
with a rare card and 2 and 3
representing a pack without a rare card.
The frequency of the number of packs
with rare cards in each trial of 7
samples in the simulation is
represented by this table.
