Answer:
Option B
Step-by-step explanation:
Given that Half of you want to go bowling and the other half want to go to a movie
So we must get probability for bowling = prob for movie
Option 1: Here P(HH) = 1/4 and P(no HH) = 3/4
SInce the two are not equal this is not fair
2) Here P(HT ) =1/4 and P(TH)=1/4 and other outcomes repeat the process
This is fine and hence this option is right
3) P(HHT) = 1/8 and P(TTT or HHH) =1/8+1/8=1/4
This is biased and hence not fair
4) P(HHH or TTT) = 1/4 and P(Other options)=3/4
Biased and hence not fair
Only option B is right.
