Conditional Strength

Indicate the weakest condition in each set. Write "None" if the conditions are unrelated by implication. Unless otherwise stated, assume all variables are ints. 1. = { x is odd && y x + 2 } { x is odd && yis odd } { x 2 0 && y + 2 } 2. { OS X 0 && y > 0 } { x > 10 || y = 0 } 4. { x is divisible by 6 } { the rightmost digit of x is even } { the sum of digits of x is divisible by 3 } 5. { -5
