    There are six possibilities for where the spinner will stop.  To figure out any particular chance, count how many times out of 6 it could happen.

    1) Any one number -- such as 3 -- has a probability of 1 in 6 or 1/6.

    2) There are three numbers less than four, so the probability of landing on one of them is 3 in 6, or 1/2. 

    3) The same is true of landing on an even number.  There are three possible stopping places that are even, so the probability is 3 in 6 or 1/2 again.

    1) you have six numbers and one of them is three so you would have 1/6 of a chance to get three

    2) infering that number doesn't include 4 you would have 1/2 (3/6) of a chance

    3) to get a even number (2,4,6) you would have 1/2 (3/6) of a chance

    I think it is 3 bacause the spinner could land on even numbers

    or it can land on all the numbers
