out of forty students there are 14 who are taking physics and 29 who r takin calculus.what is the probablity that a randomly choosen student from this group is taking only the calculus class.

• 11 are takin physics only
  26 are takin calculus only
  3 are takin both.
  prob is 26/40
  
• 11 years agoHelpfull: Yes(18) No(3)
• total students=40
  14 are taking physics
  29 are taking calculus
  students taking both=(14+29)-40=43-40=3
  therefore probability of students taking only the calculus class=(29-3)/40=26/40
