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.
I believe that 95 isn't one of the measures
Part a: subtract 48-30=18
Part b: i found it by subtracting 48 -30 because it says left over
