In a high school basketball game, a player on the home team makes two free throws. One student asks the student next to her what he thinks the probability of hitting two free throws in a row is. The student replies, "The probability of him making a free throw is probably about .6, so hitting two free throws is probably about 1.2." Why can this immediately be dismissed as incorrect?
A.The final number, 1.2, is a fraction, which can never represent a probability.
B.The probability of making a free throw can never be .6.
C.The probability of an event happening twice in a row can never be equal

anonymous · Answer

and last option is D.The final number is greater than 1, which is not a valid probability.

anonymous · Answer

The estimate is good;  .6 to sink one free throw makes sense.
If two events happen in a row, how do you represent the combined probability of both events happening?
