Answer

c,d,e,h

Work Step by Step

All probability values should be between 0 and 1 inclusive. Values greater than 1 or less than 0 cannot be considered probability outcomes. (a) Probability outcome as it is between 0 and 1 inclusive. (b) Probability outcome as it is between 0 and 1 inclusive. (c) Not a probability outcome as negative values cannot be considered probability outcomes. (d) Not a probability outcome as values greater than 1 cannot be considered probability outcomes. (e) Not a probability outcome as negative values cannot be considered probability outcomes. (f) Probability outcome as it is between 0 and 1 inclusive. (g) Probability outcome as it is between 0 and 1 inclusive. (h) $125$%$=1.25$, this is not a probability outcome as values greater than 1 cannot be considered probability outcomes. (i) $24$%$=0.24$, this is a probability outcome as it is between 0 and 1 inclusive. Therefore, c,d,e,h are not possible outcomes.
