Answer:
20/25
Step-by-step explanation:
Here, we want to calculate the probability that a student who plays an instrument is in band
The number of students who play instruments are;
25
Amongst this,
20 are in a band
So the probability of having a student who plays instrument and is in a band will be;
20/25 = 4/5
Answer:
Let there were total x people at the conference
so 32%of x is 216
32/100×x=216
x=216×100/32
x=675
So total people present at the conference were 675
Try 6.5x10^4
Pretty sure that’s it, If not I’m sorry!
