If there is a 60% chance of rain on Saturday and a 70% chance of rain on Sunday, then there is a 130% chance of rain over the weekend. (Select all that apply.) 


A. The chance of rain over the weekend is 70%, because it is the larger of the two chances given.

B. Chance is never greater than 100%.

C. The chance of rain over the weekend is 65%, because it is the average of the chances of rain on Saturday and Sunday.

D. There is not enough information given to calculate the chance of rain over the weekend.

E. The chance of rain over the weekend should be 100% because rain is always possible.



Part (b)


The probability that a baseball player hits a home run is greater than the probability that he gets a successful hit. (Select all that apply.) 


A. The probability that he hits a home run and the probability that he gets a successful hit must add up to 1.

B. These probabilities cannot be calculated, so it is impossible to say which one is greater.

C. A home run by definition is a successful hit, so the probability that he gets a successful hit must be greater than, or at least equal to, the probability that he hits a home run.

D. The probability that he gets a successful hit must be 1, since a successful hit is always possible, and therefore the probability that he hits a home run cannot be greater.

E. A home run is the only type of successful hit, so the probabilities of each must be equal.
