The prices of three sneaker styles are $48, $56, and $72. The probability of choosing the $48 sneaker style is 1/2 . The probability of choosing the $56 sneaker style is 1/8 . The probability of choosing the $72 sneaker style is 3/8 . What is the expected value of of a pair of sneakers?

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
