Answer:
[tex]\huge\boxed{\text{(B)}\ 0.41}[/tex]
Step-by-step explanation:
This table will prove to be helpful to find the probability that a student has a cell phone and is from School B.
First off, we know that a total of 1000 students were interviewed, both from School A and from School B.
We also know that 479 of those 1000 were from School B (total on the right).
Looking further into School B, we can see that 408 students from school B have a cell phone.
Therefore, we can find the probability by finding 408 / 1000.
[tex]408 \div 1000 = 0.408 \approx 0.41[/tex]
Therefore, the probability that a randomly selected student is from School B and has a phone is 0.41, or 41%.
Hope this helped!
