Question

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

Answer 1

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:

`P(\text{ no toy\rparen}=1-(13)/(18)=(5)/(18)`

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.
