find the probability that a heximal(number system with base 6 ) number when converted to its equivalent decimal value will be divisible by 10 ?

• no. in base 6 ---------------convert the no. in base 10
  1 -------- 1
  2 ------- ---- 2
  3 ----------- 3
  4 ---------- 4
  5 --------- 5
  10 ---------- 6
  11 ---------- 7
  12 ---------- 8
  13 ---------- 9
  14 ---------- 10
  
  so required probability = 1/10

• if we consider no from 1 to 10 then out of all these no. only one no . that is 5 which is when converted in decimal gives 30 , which is divided by 10
  another if we take no from 11 to 20 then no 14 gives correct ans and hence this is applicabe in fruther cases
  hence if we take probability of such solution then it will be 1/10

• 1/10 ... there will be 1 out of 10 no. which will be divisible by 10

• It does not matters which base we are converting to decimal.
  When we convert it to decimal the last digit will be any from 0 - 9 ,
  i.e. 0,1,2,3,4,5,6,7,8,9
  Since we need to find out whether the converted decimal is divisible by 10 the last digit needs to be zero (0).
  So total outcomes = 10
  i.e. (0,1,2,3,4,5,6,7,8,9)
  Favourable outcome = 1
  i.e. any number ending with zero
  So probability will be: 1/10.

• suppose the heximal number is 5 it can be converted as decimal
  5*6=30
  it is divisible by 10

• @prabhakar singh Can you give me the 10 cases ?

• 0 to 5 no. in hex at 0 get 0 decimal divisible by 10
  so 1/6
