I need help in this section please!!
MrRissso [65]

Answer:

\frac{1}{25}

Step-by-step explanation:

Probability of first yellow ball=\frac{total\ yellow\ ball}{Total\ ball}=\frac{2}{10}=\frac{1}{5}

Since first ball is again placed in the bag

Probability of second yellow ball=\frac{total\ yellow\ ball}{Total\ ball}=\frac{2}{10}=\frac{1}{5}

These two are independent events so the probability of both yellow balls==\frac{1}{5} \times \frac{1}{5} =\frac{1}{25}

I need help with the slope of this line.​
GrogVix [38]
The slope is 0.




The formula to find the slope is y2-y1 over x2-x1. If you plug in your numbers, you should have 5-5 over 9-10. Subtract this and you will get your slope!
