Question

Ashley takes her 3-year-old brother Alex into an antique shop. There are 5 statues, 4 picture frames, and 3 vases on a shelf. Alex accidentally knocks 2 items off the shelf and breaks them.
Choose the probability best described by:
1/22.

A - breaking statute, then frame
B - breaking a vase, then a statue
C - breaking 2 vases
D - breaking 2 picture frames

Answer 1

i think breaking 2 picture frames

Answer 2

breaking statue followed by frame: (5/12) x (4/11) = 5/33
breaking a vase then statue: (3/12) x (5/11) = 5/44
breaking 2 vases: (3/12) x (2/11) = 1/22
breaking 2 picture frames: (4/12) x (3/11) = 1/11

Answer 3

The product of the probabilities is the total probability:

For the vases:
\[\frac{3}{12} \cdot \frac{2}{11}=\frac{1}{22}\]

Answer 4

the answer is C- breaking 2 vases
