Answer 1

`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
