2% of the stray dogs in southfield are unlicensed. on a randomlychosen day, the southfield city animal control officer picks up 7 stray dogs. what is the probability that at least on will be unlicensed?

0.98^7 is the probability that none of them are unlicenced. So, 1 minus this probability is the probability that one or more are unlicenced.
