a, 40
b, 30
c, 32
d, 42

• 4 out of 5 Students are left handed
  total students = 40
  5 * 8 = 40
  left handed 4*8=32

• 4 out of 5 means every 10 student 2 are not left handed... so in 40 student 8 are not .... 40-8=32 student are left handed
• 9 years agoHelpfull: Yes(3) No(0)
• Probability of left handed = 4/5
  total student = 40
  total left handed = 40 *(4/5)
  = 32

• 40/5=8
  4*8=32 ans

• 4 out of 5 students are left handed
  now total students is 40.means if we divide by 5 then we get 8 [5+ 5+ 5+ 5+ 5+ 5 +5 +5=40]
  now if 4 out of 5 students are left handed then [4+4+4+4+4+4+4+4=32] are total left handy students out of 40.

• ans is 4/5*40=32
• 9 years agoHelpfull: Yes(1) No(0)
• 32
  80% are left handed
  so 80% of 40 is= 32
• 8 years agoHelpfull: Yes(1) No(0)
• 32 since 5*8 = 40 therefore required ans is 4*8=32
• 9 years agoHelpfull: Yes(0) No(0)
• 32 left handed
  
• 9 years agoHelpfull: Yes(0) No(0)
• for every 10 students we get 8 left handed hence for 40 students we get 8*4=32 left handers.
• 9 years agoHelpfull: Yes(0) No(0)
• 4 out 5 are left handed so 4/5*40=32 would be left handed

• x+2+y+2+z+2=9
  x+y+z=3
  3+3-1c3-1=5c2

• C- 32
  
  In 40 ,5 is divisible 8 times...for every 5 there are 4...so,8*4=32
