Answer:
Probability of having the double sided coin is 1 %
Probability of getting heads on the next flip is 50%
Step-by-step explanation:
Based on the information given to us in the question we have a total of 100 coins in the bag and only 1 is double heads. Therefore the probability of you picking the double sided coin is or 1 % . This probability is not affected by the fact that the coin you chose got heads 7 times in 7 flips.
Since a coin has 2 sides and you do not know whether the coin you have is the double sided coin then you have to assume that it is a normal 2 sided coin. Therefore a normal 2 sided coin has a probability of or 50% with every flip of getting heads.
