Question

the question is in the pic! Also, you have to give the answer in simplified, decimalized, and percentaged form!!

Answer 1

The total number of pieces in the domino is 28.

a)

The number of pieces that have an odd number of dots is 12, so the probability of choosing a piece with an odd number of dots is:

$P=\frac{12}{28}=\frac{3}{7}=\text{0}.4286=42.86\text{\%}$

b)

The number of pieces that have 2 dots is 2, so:

$P=\frac{2}{28}=\frac{1}{14}=0.0714=7.14\text{\%}$

c)

The number of pieces that don't have 7 dots is 25, so:

$P=\frac{25}{28}=0.8929=89.29\text{\%}$

d)

The number of pieces that have at most 8 dots is 22, so:

$P=\frac{22}{28}=\frac{11}{14}=0.7857=78.57\text{\%}$

e)

The number of pieces that have more than 10 dots is 2, so:

$P=\frac{2}{28}=\frac{1}{14}=0.0714=7.14\text{\%}$

f)

The number of pieces that have a number of dots multiple of 4 is 7, so:

$P=\frac{7}{28}=\frac{1}{4}=0.25=25\text{\%}$
