Question

PlEaSe HeLp!

Answer 1

So we know the student plays an instrument, we are trying to find the probability of the students who play a sport. We know a total of 11 students play an instrument. And we want the number of students who play a sport, which is 2. So the probability is 2/11. (Hoped this helped)

Answer 4

So kinda like the other one we know that they have a sister and we want to know the probability of brother to sister. So out of the students who have a sister is 5. And we are looking for students who also have a brother and a sister, which is 3. So the probability is 3/5.
