Find the probability if a two digit number multiplied by 3 but not 5

• sample space of 2 digit number = (99-10)+1 = 90
  probability of number multiplied by 3 but not 5 = total no. multiplied by 3 - total no. multiplied by 5
  = 30 - 6=24
  so, probability= 24/90 = 4/15

• 4/15
  
  Total two digit numbers are 90 i.e. from 10 to 99
  numbers multiple of 3 are 12, 15, 18, ......., 99 so 12+(n-1)3=99, n=30
  numbers multiple of 3 & 5 both are 15,30,45,60,75,90 total 6
  So two digit numbers multiple of 3 but not of 5 are 30-6=24
  Probability=24/90=4/15

• Ans : 24/30 = 4/5
  2 digits numbers with 3 as factor = 30 (100/3 - 3)
  2 digit numbers with 3 and 5 as factor i.e factor 15 = 100/15=6
  So probablity = No of numbers with 3 as factor and not 5 / Total No of numbers with 3 as factor
  =24/30=4/5

• I think A must be zulu...why??....cz he said that he can be a zulu or a hutu....he gave two options....never mentioned exact one...dats why he s d zule for sure...;)
  Den B told the damn truth about A....so he can be zulu...
  now what about C.....
  If A is considered to be zulu....den C has to be hutuuuuuuuuuuuuuuuu.............
  
  
  ......Got it??
