Pre-requiste to understand my answer :
1) Equal roots condition in quadratic equation.
2) bit patience and adventurous mind.
Total No. of outcomes = 6×6×6= 216.
No. of favorable outcomes = 5
Probability = 5/216
Hope, you may understand my writing and it helps you .
Well , the question can become little better if probability of real roots was asked instead of equal roots.
Bye !
