A personal identification number (PIN) consists of 3 numbers 0 – 9. What's the probability someone's PIN number consists of only 1 number. For example 000, 111, 222, etc.

Step-by-step explanation:

given data:

numbers contained in pin = 3

numbers pin can be gotten from = 0-9

solution:

0,1,2,3,4,5,6,7,8,9 = 10

probability the pin consist of only 1 number

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
