A hypothetical wi$-$fi transmission can take place at any three speeds depending

on the condition of the radio channel between a laptop and an access point. The speeds

are high $($h$)$ at $54$ Mb$/$s$,$ medium $($m$)$ at $11$ Mb$/$s$,$ and low $($l$)$ at $1$ Mb$/$s$.$ A user of the

wi$-$fi connection can transmit a short signal corresponding to a mouse click $($c$),$ or a

long signal corresponding to a tweet $($t$).$ Consider the experiment of monitoring wi$-$fi

signals and observing the transmission speed and the length. An observation is a two

letter word, for example, a high$-$speed, mouse$-$click transmission is hc$.$

$$ What is the sample space of this experiment?

$$ Let A$1$ be the event "medium speed connection". What are the outcomes in this

event?
