Assume that 70% of teenagers who go to take the written drivers license test have studied for the test. of those who study for the test 95% pass; of the those who do not study for the test, 60% pass. what is the probability that a teenager who passes the written drivers license test did not study for the test?

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}  

5⋅2  

x

=240
