What's the probability of getting at least one blue marble between my two draws? [closed]

So if I have a bag with $$5$$marbles in it with different colors. Red, orange, purple, blue and green. I draw a marble, put it back and then draw again. What's the probability of getting at least one blue marble between my two draws?

• Where are you having trouble with this? Please show what you have tried, or at least think you should do. – Graham Kemp May 4 at 2:15
• If there are only two draws there can be nothing in between. – user May 4 at 8:55

Probability of getting no blue in two draws is $$(\frac{4}{5})^2$$ so getting at least one blue has $$P=1-(\frac{4}{5})^2=\frac{9}{25}$$.
