Question

Anna, Irina, Avel, and Vlad are going on a road trip. The following table shows an incomplete probability model for who will be driving during any given kilometer.

Answer 1

Answer:okok i know

Step-by-step explanation:dfrac{3}{8}

2. 240 km

Step-by-step explanation:

Anna drives \dfrac{1}{8}, Irina drives \dfrac{3}{8}, Vlad drives \dfrac{1}{8}, then Avel drives

1-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8}{8}-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8-1-3-1}{8}=\dfrac{3}{8}.

If the road trip involves 640 km of driving, then Avel drives

640\cdot \dfrac{3}{8}=80\cdot 3=240\ km.

Answer 2

Answer:

. \dfrac{3}{8}

2. 240 km

Step-by-step explanation:

Anna drives \dfrac{1}{8}, Irina drives \dfrac{3}{8}, Vlad drives \dfrac{1}{8}, then Avel drives

1-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8}{8}-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8-1-3-1}{8}=\dfrac{3}{8}.

If the road trip involves 640 km of driving, then Avel drives

640\cdot \dfrac{3}{8}=80\cdot 3=240\ km.
