Suppose you're playing hide and seek in a big house with 4 rooms upstairs and 5 rooms downstairs. You've looked in 2 of the downstairs rooms and know the hider is not those rooms. What is the probability the hider is downstairs given this information? (Assume equally likely outcomes).

3/7

Step-by-step explanation:

1. there were a total of 9 rooms but you minus two due to the fact the hider isnt there and so you are left with 7

2. You also minus two from five and that gives you three

3. they ask for only downstairs so it would be 3/7

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

no
