Question

A biased coin is tossed 40 times. Out of those 40 tosses, the coin landed on heads 12 times.

Find the probability of the coin landing on tails.

Answer 1

Explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.
