to find any probability just find the total and then divide that by the number of whatever you're checking for, eg. parkour backgrounds.
A)
7+3+4+6 = 20 total backgrounds
6 parkour backgrounds.
20/6 is your answer.
B)
6 + 10 + 5 = 21 total marbles
10 + 6 = 16 non yellow marbles
21/16 is your answer.
C)
6 + 10 + 5 = 21 total marbles
10 blue marbles
21/10 or 2.1 is your answer.
Twice. Dividing by ten will move the decimal point one place to the left. Rather than dividing by ten twice, you can divide by 100 once.
The correct answer would be a Right triangle
