Each day, Finian takes either a bath or a shower in the morning. S represents shower, and B represents bath.

What is the sample space of his morning ritual for three days in a row?

 

Answer choices:

  • {S, B, S}
  • {SSS, SSB, SBB, SBS, BBB, BBS, BSS, BSB}
  • {SS, SB, BB}
  • {SSS, SBS, SBB, SSB, BBB, BSB}

Notice that he has   2 options every morning  ( B or S )

 

So...we should expect

 

(2) * ( 2)  * (2)    =  8  possible outcomes  

 

Only the second choice has 8 possible outcomes
