Respuesta :

Let the probability of rolling a six be x.

Given that the probability of rolling a three is the same as rolling a six.

The probability of rolling a three=x

Given that the probability of rolling a five is 3 times that of rolling a three.

The probability of rolling a five =3x.

Given that the probability of rolling a one, two, or four is 3 times that of a six.

The probability of rolling a one =3x.

The probability of rolling a two =3x.

The probability of rolling a four =3x.

We know that the total probability is 1.

The sum of the probability of one, two, three, four, five, and six =1

[tex]3x+3x+x+3x+3x+x=1[/tex]

[tex]14x=1[/tex]

Dividing both sides by 14, we get

[tex]\frac{14x}{14}=\frac{1}{14}[/tex]

[tex]x=\frac{1}{14}[/tex]

Substitute x=1/14 to get the required probabilities.

The probability of rolling a one is

[tex]3x=3\times\frac{1}{14}=\frac{3}{14}[/tex]

The probability of rolling a two is

[tex]3x=3\times\frac{1}{14}=\frac{3}{14}[/tex]

The probability of rolling a three is

[tex]x=\frac{1}{14}[/tex]

The probability of rolling a four is

[tex]3x=3\times\frac{1}{14}=\frac{3}{14}[/tex]

The probability of rolling a five is

[tex]3x=3\times\frac{1}{14}=\frac{3}{14}[/tex]

The probability of rolling a six is

[tex]x=\frac{1}{14}[/tex]
