Scam calls are becoming an infuriating part of people$$s daily lives. According to Truecaller, Americans lost $$30$ billion from phone scams in $2021,$ which is $$10$ more than the total amount lost in $2020.$ Neighborhood spoofing $($use a number starting with your area code$)$ is the most common among all scams. Now suppose

$0\mathrm{.}5$ of your incoming phone calls are scam calls. Among the scam calls

$0\mathrm{.}8$ use neighborhood spoofing. Of your non$-$scam incoming phone calls,

$0\mathrm{.}6$ are from numbers that start with your area code.

Given that a randomly selected incoming phone number starts with your area code, what$$s the probability it is not a scam call? Please round your answer to $2$ decimal place.

Hint: You can draw a tree diagram on your scratch paper to illustrate the information.
