Problem number one. Basil wants to write the word mathematics on a sheet of paper. He wants to color the different letters with different colors  and the same letters with the same color. How many colors will he need? 7, 8, 9, 10, or 13? Here is the word mathematics. And we are going to color in all the different letters  starting with M and then moving on to A, then T, then H, then E. And the second M will be the same color as the first M because they are the same letter.  The A and the T also have duplicates so they are also the same color. Then we have I, C, and S. So now we see we have 1, 2, 3, 4, 5. So these three are repeats.  And then we have 6, 7, 8. There are eight colors in total which means our answer is B.

Video Summary

Basil wants to write the word "mathematics" on a sheet, coloring different letters with different colors, and same letters with the same color. The letters in "mathematics" are M, A, T, H, E, M, A, T, I, C, S. M, A, and T have duplicates. Therefore, colors are needed for M, A, T, H, E, I, C, S. That totals 8 different letters, so Basil will need 8 colors. The correct answer is 8.
