TS EAMCET · Maths · Probability
A person tossing a biased coin indefinitely wins the game by getting head for the first time. The probability that he wins the game in odd number of tosses is \(3 / 4\). If 5 such coins are tossed at a time then the probability that head appears on all the coins is
- A \(\frac{32}{3125}\)
- B \(\frac{243}{3125}\)
- C \(\frac{1}{243}\)
- D \(\frac{32}{243}\)
Answer & Solution
Correct Answer
(D) \(\frac{32}{243}\)
Step-by-step Solution
Detailed explanation
Let the probability getting head \(=p\) probability of not getting head \(=1-p\) Given, he wins the game in odd number of tosses…
