Respuesta :

Answer:

Number of different ways can she spend her Saturday = 54

Step-by-step explanation:

Jane has to do three types of things - Work out , Eat and Read a book

In Work out -

She either lift weights, run, or hike

In Eating -

She will choose 1 of the 6 restaurants near her home

In Reading -

Read either Harry Potter, Catcher in the Rye, or Girl on the Train

Number of ways in which she can work put = ³C₁ = [tex]\frac{3!}{1! (3-1)!} = \frac{3!}{2!} = 3[/tex]

Number of ways in which she can eat = ⁶C₁ =  [tex]\frac{6!}{1! (6-1)!} = \frac{6!}{5!} = 6[/tex]

Number of ways in which she can read =  ³C₁ = [tex]\frac{3!}{1! (3-1)!} = \frac{3!}{2!} = 3[/tex]

So, Total number of ways = 3×6×3 = 54
