Knowledge check (probability) this is math not chemistry. I am looking at the tab

Answer:
5:13
Explanation:
Given that the probability of the box having a toy = 13/18
Therefore, the probability of the box not having a toy:
[tex]P(\text{ no toy\rparen}=1-\frac{13}{18}=\frac{5}{18}[/tex]The odds against an event is given as the ratio of the Number of unfavorable outcomes to number of favorable outcomes.
• Number of Unfavourable Outcomes = 5
,• Number of favourable Outcomes = 13
Thus, the odds against the box having a toy is 5:13.
