4 – digit number greater than 5000 are randomly formed from the digits 0, 2, 3, 5 and 7. The probability of forming a number divisible by 5 when the digits are repeated is ______
    Correct answer is '0.39-0.4'. Can you explain this answer?
    Verified Answer
    4 – digit number greater than 5000 are randomly formed from the ...
    For a number to be greater than 5000, d1 should be filled with either 5 or 7
    ∴ Total numbers formed when the digits are repeated = 2 × 5 × 5 × 5 = 250
    total cases = 250 -1 = 249 ( case of 5000 is not included)
    Now, For the number to be divisible by 5, unit digit d4 should be either 0 or 5.
    ∴ Total no. of ways = 2 × 5 × 5 × 2 = 100
    favorable cases = 100 - 1=9 ( 5000 is not included))
    ∴Required Probability =
