Know the Answer?

Khalil Banks · Answer 1

I would go with B

she cant see the shapes so C would be wrong

also A makes absolutely no sense

Athena Schneider · Answer 2

B. because she can feel the shapes

Step-by-step explanation:

A random sampling is a technique where all samples have the same probability to be selected.

In this case, the sample is about shapes. As you can deduct, Sylvia is able to feel the shape she's going to select, which means she can choose which one is gonna be selected, that's makes the sampling not random.

Therefore, the answer is B.
