Sammy fell off her bike oh no! what should we do now? HAHA lol

never ride a bike again

Step-by-step explanation:

Help SAMMY !! Sammy might be hurt and might have to go to the doctor

Since it is stated that the machine he bought only predict about 80%. thus, about 20% are still possible that there are oils in the land that he owned.
in a 100% value = 80% were the 0 possibillites detected by the machine and 20% are still the possibility that it has an oil.
=> 80% = 0.80
=> 20% = 0.20
in the given choices. letter b has the closest value to the 20% that we expected.
thus, let's have b as an answer.
