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:3/8

Step-by-step explanation:Khan academy

Answer 2

Answer:

$\frac{3}{8}$

Step-by-step explanation:

P (Anna) + P (Irina) + P ( Avel) + P (Vlad) = $1$

$\frac{1}{8}+\frac{3}{8}$ $+$ P (Avel) $+$ $\frac{1}{8}$ $= 1$

P (Avel) $= 1 - \frac{1}{8} - \frac{3}{8} - \frac{1}{8}$

P (Avel) $= \frac{3}{8}$

The probability that Avel will be driving during any given kilometer is $\frac{3}{8}$.
