Answer 1

Let A be the event that the randomly chosen boy from the school play basketball.
Let B be the event that the randomly chosen boy from the school play soccer.
It is given that,

• Here, we are to find, the probability that the randomly chosen boy from the school plays at least one of those sports. That is, we are to find,
  
  
  
  
  
  
• Here, we are top find the percentage of soccer player who also play basketball.
  That is we are to find:
  
  
  
  
  
  
  
• For the two events to be independent,
  
  
  Now,
  
  
  
  
  
  Hence, the events are not independent.
