Agame has 15 balls for each of the letters b, i, n, g, and o. the table shows the results of drawing balls 1,250 times.

letter frequency
b 247
i . 272
n 238
g 241
o 252

for which letter is the experimental probability closest to the theoretical probability?
a. i
b. n
c. g
d. o

Theoretically, each letter should have the same probability of occurring since there are 15 of each. There are 5 letters that can be drawn, so there is a total of 75 balls, and each letter has a probability of being drawn.

This means one would expect a theoretical frequency of , i.e. any given letter should get drawn 250 times, which means the answer is D.
