Respuesta :

  • |S|=14
  • |E|=7

Now

[tex]\\ \rm\Rrightarrow P(E)=\dfrac{|E|}{|S|}[/tex]

[tex]\\ \rm\Rrightarrow P(E)=\dfrac{7}{14}=1/2[/tex]

Answer:

[tex]\mathsf{Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ outcomes}}[/tex]

Given:

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

[tex]\implies \mathsf{Probability \ of \ red\ hair= \dfrac{7}{14}=\dfrac12=0.5}[/tex]
