</span>Let event A be defined as randomly
choosing someone who picked cats or dogs as their favorite pet. Let
event B be defined as a randomly

P(A) = P(choosing cat) + P(choosing dog) =
P(NOT A) =
P(B and NOT A) = P(males that did not choose cat or dog) =
P(B | NOT A) =

<span>Petey

Determine if Petey should make the investment, and find the expected
value of the investment.
If his investment increases by 10%, the value of the investment will be 1.1 x $19 = $20.90 with a probability of 30% or 0.3
The expected value of the investment is given by
Therefore, Petey should not make the investment as there is an expectation of a loss from the investment.
