Answer:

$\frac{1}{4}$

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 = $\frac{50}{200}=\frac{1}{4}$
