Answer: (b) 0.125
Step-by-step explanation: add up the percentages of each color besides blue.
Yellow=5% or 0.5
green=25% or 0.25
red= 1.25% or 0.125
0.5+0.25+0.125=0.875
Now, we have to find out what blue's percentage is. So, blue is a half of a quarter which means we divide it by 2 since red an blue's percentage together equals to a quarter.
0.25/2= 0.125 Let's add it to 0.875 and see if it equals a whole
0.875+0.125=1
So, the probability of landing on blue would be 0.125
