Answer 1

The probability is 1/5 or a 20% chance.

Answer 2

Answer: $\dfrac{1}{5}$

Step-by-step explanation:

Given : A family has five members: a mom, a dad, two sisters, & a brother.

If the family lines up single file, then the number of persons can be at the front of the line = 5

Now, the probability that the mom is at the front of the line :-

$\dfrac{\text{desired outcomes}}{\text{total outcomes}}\\\\=\dfrac{1}{5}$

Hence, the probability that the mom is at the front of the line= $\dfrac{1}{5}$
