successfully makes a free throw 56.5% of the time. Say he decided to shoot two free throws
in practice, assuming that his free throws are independent to one another, what is the
probability that he:
--, Dwight Howard has a free throw percentage of 56.5% which means he
a. makes the first and then misses the second?
b. misses both of his free throws?

Two archery targets are divided into 3 sections that contains numerical values, as
shown below. When an arrow is shot in a target, it goes to the blue section 55% of the time,
the red section 35% of the time, and the yellow section 10% of the time. Say we shot an
arrow on each target. Let the random variable X represent the sum of the two values where
the arrows landed. What is the probability distribution table of the variable random variable
X?
