Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The change of something happening will be in the form:
Number of that thing/Total number of things
Here, the change of bead being blue is:
The number of blue beads / total number of beads
Hence,
Number of Blue Beads = 50
Total number of beads = 100 + 50 + 50 = 200
Hence,
The chance of bead being blue = [tex]\frac{50}{200}=\frac{1}{4}[/tex]
