Hello I need help with this Stats question. Thank you

In an experiment, you flipped a coin 3 times and the result was (H,H,H). You have 2 hypotheses. The first one is that the coin is fair (the probability of the coin landing heads is equal to 0.5). The second hypothesis is that the coin is biased and that the probability of landing heads is 0.75. What is the Bayes factor in favor of hypothesis 1 relative to hypothesis 2? O 8/27 O 3/4 O 1/2 O 12/27
