check all below
Step-by-step explanation:
#1
1/6)^3
1/26 so answer 1 on number one
#2 what the heck is this 65+75= 140 not 120
65/120 = 54.16666% * 12600 = 6825 so 3
or 65/140 = 46.428% * 12600 = 5850
#3 number 4 makes the most since sense you get the WHOLE POPULATION
#4 1/5*1/2 or 1/10 = .10 * 100% = 10% or 3
#5
6+2+8+4 = 20
2 red marbles
2/20 = 1/10 = .10 * 100% = 10% or 2
Stick =5
1 glass =1
snow=10
5+1+10= 16
