Answer:
The conditional probability that I get four heads given I pulled out the weighted coin = 0.2401
Step-by-step explanation:
Probability of getting 4 heads from 4 trials for a fair coin = 0.5⁴
But given that it is the weighted coin that is pulled out,
The probability of getting 4 heads from 4 trials = 0.7⁴ = 0 2401
