Your experiment is to select the day of the week that it will rain. What is the probability that you will select a day that begins with the letter T? 13 5 7 2 ОООО 12 2 7 It cannot be determined. I don't Know

Respuesta :

[tex]P=\frac{2}{7}[/tex]

Explanation

Step 1

the probabily of a event can be calculated:

[tex]P=\frac{favorable\text{ outcomes}}{\text{total outcomes}}[/tex]

Let

favorable outcomes=days that begins with the letter T

Hence

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

and

[tex]\text{total outcomes= 7}[/tex]

because the week has 7 days

Step 2

Replace

[tex]\begin{gathered} P=\frac{favorable\text{ outcomes}}{\text{total outcomes}} \\ P=\frac{2}{\text{7}} \\ P=\frac{2}{7} \end{gathered}[/tex]

I hope this helsp you
