Question

3 digit number is formed with the digits 1,2,3,4,5 at random what is the probability that it is divisible by 5

Answer 1

Total  no. of possible outcomes = ⁵ P₃ = 60

after fixing 5 at the end position or ones place 

we are left with 4 numbers 

now we are to choose 3 from 4 i.e ⁴P₃

so, no. of favorable  outcomes =  ⁴P₃ = 24  


now , probability = no. of favorable outcomes /  total no. of possible outcomes 

hence ,  probability = 24/60 = 4/ 10 = 2/5 ans.

plzzzzzzz.    mark brainliest , i need it
