If a biased coin with 69% chance of getting heads, is tossed then what is the probability of getting a tails.

If a biased coin with 69% chance of getting heads, is tossed then what is the probability of getting a tails. Correct Answer 0.31

Given

Coin is biased.

Probability of getting heads = 69% = 0.69

Concept used

P(Not Favourable) = 1 - P(Favourable)

Calculation

P(Tails) = 1 - P(Heads)

P(Tails) = 1 - 0.69

⇒P(Tails) = 0.31

∴ 0.31 is required answer
