If there are 7 sets of the notes d e f and g 8 setsof a b c written piece paper placed in cup person draws one what his chances getting c?

To calculate the probability of drawing a "c" note from the cup, we need to determine the total number of notes and the number of "c" notes available.

Total notes: There are 7 sets of d e f and g, and 8 sets of a b c. Each set consists of 3 notes, so the total number of notes is:

(7 x 3) + (8 x 3) = 21 + 24 = 45 notes.

Number of "c" notes: There are 8 sets of a b c, and each set contains one "c" note. Therefore, the number of "c" notes is:

8 x 1 = 8 notes.

Now we can calculate the probability of drawing a "c" note:

Probability = Number of "c" notes / Total number of notes

Probability = 8 / 45

Therefore, the chances of getting a "c" note from the cup are 8 out of 45, or approximately 0.178 or 17.78%.
