To predict the number of advertisements Josephine will receive in the next 100 e-mails, we can use the proportion of advertisements she previously noted.
Out of 10 e-mails, 7 were advertisements, which gives us a ratio of:
\[
\text{Proportion of advertisements} = \frac{7}{10} = 0.7
\]
To find out how many advertisements she might expect in the next 100 e-mails, we multiply this proportion by 100:
\[
\text{Expected number of advertisements} = 0.7 \times 100 = 70
\]
Therefore, Josephine can predict that she will receive **70 advertisements** in the next 100 e-mails.
The correct answer is: **She will receive 70 advertisements.**
