    a bowl contians 1000 tickets numbered b/w 1-1000 what is the probability thats a number between 10 and 90?

    81/1000
    80/1000
    79/1000
    82/1000
    none of the above

    i thought it be D because it says BETWEEN so i figured not including 10 and 90 but the answer is A...are we supp to always include the number they give us in a between question or w/e

    well 10 is between 10 and 90 and so is 90 so therefore you would include both numbers. Perhaps the question could have been worded a little better so say 10 and 90 inclusive but either way both numbers are usually included. According to your logic how do you get 82/100.
