Consider U = {x\x is a positive integer greater than 1}.

Which is an empty set?

{xx U and is prime}

O {xxe U and 2x is prime}

O {x}x e U and 1 x can be written as a fraction}

O {x\x € U and 2x can be written as a fraction}

ok then what happened.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
