Answer 1

16 over 27 sorry if i’m wrong.

Answer 2

`(16)/(27)`

Explanation:

From the table, we notice that the total number of students is:

`3+10+8+6=27`

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

`10+6=16`

So, the probability that a randomly chosen student does not have a brother is:

`\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=(16)/(27)`
