Question

A young mother takes her 3-year old child into a gift shop. There are 4 statues, 3 picture frames and 3 vases on a shelf. The child accidentally knocks two items off the shelf and breaks them. What is the probability that the child broke a picture frame, then a vase? please show me the steps

Answer 1

First add 4+3+3=10 then 3+3=6
6/10 is the probability of breaking a vase and picture frame.

Answer 2

but the answer is 1/10. i don't know how to get it

Answer 3

oh, well its impossible to get 1/10 with two things.

Answer 4

A. 2/15 B. 1/15 C. 1/10 D.1/5
C is right

Answer 5

look its very easy
first if we see there are 10 things

this digram shows that ist out of 10 any thing can fall and second except that first thing other 9 things can fall.
so in case to get total no. of outcomes we will multiply 10*9=90
and by question we need only those outcomes in which first picture breakes then vase.
this shows that first out of three pictures any one can fall and in second anyone of three vase one can fall
so total no. of favarable outcomes will be 3*3=9
so the probability will be=favarable outcomes/total out comes
=9/90=1/10
