A game 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.
Mariana [72]

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 \dfrac{15}{75}=\dfrac15 of being drawn.

This means one would expect a theoretical frequency of \dfrac{1250}5=250, i.e. any given letter should get drawn 250 times, which means the answer is D.

What is 2 divided 1 6/7 ? Please answer
Aliun [14]
If you would like to divide 2 by 1 6/7, you can do this using the following steps:

2 / 1 6/7 = 2 / 13/7 = 2/1 / 13/7 = 2/1 * 7/13 = 14/13 = 1 1/13

The correct result would be 1 1/13.
