Respuesta :

Answer: 15.7%

Explanation

The probability of an event A is given by:

[tex]P(A)=\frac{\text{ occurence of events A}}{\text{total occurrences}}[/tex]

In our case, event A is rolling the number 1. Thus, we have 42 occurrences, while the total occurrences are:

[tex]\text{ Total occurrences}=42+44+45+44+47+46=268[/tex]

Then:

[tex]P(A)=\frac{42}{268}=0.1567[/tex]

Changing to percent:

[tex]0.157\times100\%\approx15.7\%[/tex]
