Do you think that the formula p=6n+1, where n, is a whole number, will produce a prime number more than 50% of the time? Give evidence to support your conclusion

    That sounds pretty advanced for an elementary class. One way you could start to solve this is to use a few different values for n and see what you get. Using n=1,2,3 we get p=7,13,19. Do that for a bunch of numbers (a spreadsheet program like Excel or Openoffice Calc will help with this) and see how many are prime.

    solution
    n= 1,2,3
    formula P=6N+1
    Now put n=1
    p=6(1)+1
    p=6+1
    p=7

    now put n=2
    P=6n+1
    p=6(2)+1
    p=12+1
    p=13

    and so on so forth
