P=(2)/(7)

Step-by-step explanation

Step 1

the probabily of a event can be calculated:


P=\frac{favorable\text{ outcomes}}{\text{total outcomes}}

Let

favorable outcomes=days that begins with the letter T

Hence


\begin{gathered} \text{favorable outcomes=}\lbrace Tuesday,thursday\rbrace \\ \text{favorable outcomes=}2 \end{gathered}

and


\text{total outcomes= 7}

because the week has 7 days

Step 2

Replace


\begin{gathered} P=\frac{favorable\text{ outcomes}}{\text{total outcomes}} \\ P=\frac{2}{\text{7}} \\ P=(2)/(7) \end{gathered}

I hope this helsp you
