Answer 1

I really need help in this one!
possible answers:
3/11
36/121
6/11

Answer 2

Total Students in the class: 6 + 5 = 11

Now, firstly, find the probability of selecting a boy:

P(B) = 5/11

Now, One boy is selected, so number of students left behind = 11 - 1 = 10

So, from total of 10 students, Find the probability of choosing a Girl:

P(G) = 6/10

So, Probability of Selecting a boy and then a girl will be:

\[P(A)*P(B) = \frac{5 \times 6}{11 \times 10}\]

\[= \frac{30}{110} = \frac{3}{11}\]

Answer 3

what will be the probability of selecting a boy and then a girl?
