SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the formula for calculating probability

[tex]P(event)=\frac{number\text{ of favorable outcomes}}{number\text{ of possible outcomes}}[/tex]

STEP 2: State the number of possible outcomes

[tex]\begin{gathered} A\text{ die has 6 faces numbered 1,2,3,4,5,6} \\ Therefore,\text{ the number of possible outcomes will be 6} \end{gathered}[/tex]

STEP 3: Answer question A

Rolling a number less than 7

[tex]\begin{gathered} Numbers\text{ less than 7}\Rightarrow6,5,4,3,2,1 \\ n(numbers\text{ less than 7\rparen}\Rightarrow6 \\ \\ By\text{ substituting the values into the formula in step 1,} \\ P(Rolling\text{ a number less than 7\rparen}\Rightarrow\frac{6}{6}=1 \\ \\ Percentage\Rightarrow\frac{1}{1}\times100=100\% \end{gathered}[/tex]

Hence,

Possible outcomes are 6,5,4,3,2,1

Probability = 1

Probability = 1.0 as decimal

Probability = 100% as percentage

STEP 4: Answer Question B

Rolling an 8

[tex]\begin{gathered} Possible\text{ outcomes}\Rightarrow8 \\ n(8)\Rightarrow0 \\ Probability=\frac{0}{8}=0 \\ Percentage=0\times100\%=0\% \end{gathered}[/tex]

Hence,

Possible outcome is 0 since there is no face of the die having 8

Probability = 0

Probability = 0.0 as decimal

Probability = 0% as percentage

STEP 5: Answer Question C

Rolling a number greater than 4

[tex]\begin{gathered} Possible\text{ Outcomes}\Rightarrow5,6 \\ n(Possible\text{ outcomes\rparen}\Rightarrow2 \\ Probability=\frac{2}{6}=\frac{1}{3}\approx0.333 \\ Percentage=\frac{1}{3}\times100=\frac{100}{3}=33.33\% \end{gathered}[/tex]

Hence,

Possible outcomes are 5,6

Probability = 1/3

Probability = 0.333 as decimal

Probability = 33.33% as percentage

STEP 6: Answer Question D

Rolling a number other than 6

[tex]\begin{gathered} Possible\text{ outcomes}\Rightarrow1,2,3,4,5 \\ n(Possible\text{ outcomes\rparen}\Rightarrow5 \\ Probability=\frac{5}{6}=0.8333 \\ Percentage=\frac{5}{6}\times100=83.33\% \end{gathered}[/tex]

Hence,

Possible outcomes are 1,2,3,4,5

Probability = 5/6

Probability = 0.8333 as decimal

Probability = 83.33% as percentage
