Step-by-step explanation:

EDIT!: someone else who probably has a better understanding than me answered this and I've been doing this all wrong lol please ignore this .w.

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.
