Answer 1

Given:

A storeowner made a list of number of greeting cards sold last month.

The store sold 167 thank-you cards, 285 birthday cards and 56 blank cards.

Required:

What is the probability that the next customer will buy a blank card expressed as a percent?

Step-by-step explanation:

We will find total number of cards sold as:

167 + 285 + 56 = 508

Now we will find percentage of each type of card sold as:

`\begin{gathered} Percenatge\text{ of thank you cards sold =}(167)/(508) \\ =0.33^\% \end{gathered}`
`\begin{gathered} Percentage\text{ of birthday card sold =}(285)/(508) \\ =0.56 \end{gathered}`

Percentage of blank cards sold

`\begin{gathered} =(56)/(508) \\ =0.11 \end{gathered}`

Answer:

Hence, in percent probability of sold blank card is 11%.
