An archer makes two attempts to hit a target, and the probability that he hits the target on any one attempt is $\frac{1}{3}$13.

What is the probability that the archer will miss the target on both attempts?

A class contains $5$5 girls and $6$6 boys. Two are selected for a class committee. What is the probability that a girl and boy are selected?

If two events are independent, then

$P$P$($($A$A and $B$B$)$) $=$=

### Outcomes

#### CC.2.4.HS.B.7

Apply the rules of probability to compute probabilities of compound events in a uniform probability model.

#### A1.2.3.3.1

Find probabilities for compound events (e.g., find probability of red and blue, find probability of red or blue) and represent as a fraction, decimal, or percent.
