Cam you look at this picture. i really need for #2, #5, #8, #9, #10

# 2 is true
# 5 is 0.375 
#8 is 8 solutions
#9 is %25
#10 is %37.5

hope this helps

for number 2: 4 times 4 equals 16 is that's why its the square root of 16. 
for number 8: with red there are 3 options plus the red option so that's 4 plus the same thing with blue so that's 8.
for number 9: there is a 2/8 chance of getting that. 2/8= 25%
for number 10: there is a 3/8 chance of landing on it. 3/8= 37.5%
