Provide solution for RD Sharma Maths Class 12 Chapter 30 Probability Exercise 30.3 question 9 sub question (ii).

Answers (1)

Answer: 0

Hint: \text{Probability}=\frac{\text{No. of outcomes}}{\text{Total no.of Outcomes }}

Given events,

            A=No tail appears

            B=No head appears

Solution:

Clearly,

\begin{aligned} &A=\{(H, H)\} \\ &B=\{(T, T)\} \end{aligned}         

\begin{aligned} &A \cap B=\{\phi\} \\ &P(A)=2 \\ &P(B)=2 \end{aligned}

Required Probability =P\left(\frac{A}{B}\right)=\frac{P(A \cap B)}{P(B)}=0
