Question

Laura is a songwriter. The table shows the number of songs she wrote in each of the past 5 months. Use the information in the table to create a probability distribution table.

Answer 1

`\begin{array}{ccccc}\text{January}&\text{February}&\text{March}&\text{April}&\text{May}\\(3)/(20)&(5)/(20)&(2)/(20)&(8)/(20)&(2)/(20)\end{array}`

Explanation:

During 5 months Laura wrote

3+5+2+8+2=20 songs.

1. The probability that the song was written in January is
`(3)/(20).`

2. The probability that the song was written in February is
`(5)/(20).`

3. The probability that the song was written in March is
`(2)/(20).`

4. The probability that the song was written in April is
`(8)/(20).`

5. 1. The probability that the song was written in May is
`(2)/(20).`

The probabolity distribution table:

`\begin{array}{ccccc}\text{January}&\text{February}&\text{March}&\text{April}&\text{May}\\(3)/(20)&(5)/(20)&(2)/(20)&(8)/(20)&(2)/(20)\end{array}`
