Please Solve R.D. Sharma class 12 Chapter 30 Probability  Exercise Multiple Choice Questions Question 15 Maths Textbook Solution.

Answers (1)

Answer: (b)

Hint: You must know the rules of finding probability.

Given: Coin tossed three times.

A = Two heads come

B = Last should be head

Solution: S = [(HHH), (HHT), (HTH), (HTT), (THH), (THT), (TTH), (TTT)]

P(A) = P(2 heads) = \frac{3}{8}

P(B) = P(Last should be head) = \frac{4}{8}

\mathrm{P}(A \cap B)=\frac{2}{8}=\frac{1}{4} \neq P(A) P(B)

Thus A and B are dependent.
