Answer:


\mathsf{Probability \ of \ an \ event \ occurring = (Number \ of \ ways \ it \ can \ occur)/(Total \ number \ of \ outcomes)}

Given:

  • Total number of outcomes = total number of clients = 14
  • Number of ways it can occur = number of clients with red hair = 7


\implies \mathsf{Probability \ of \ red\ hair= (7)/(14)=\frac12=0.5}

  • |S|=14
  • |E|=7

Now


\\ \rm\Rrightarrow P(E)=(|E|)/(|S|)


\\ \rm\Rrightarrow P(E)=(7)/(14)=1/2
