Explanation:

x = number of siblings

We add the probability values that correspond to x = 0 and x = 1, which is when the person has 0 siblings and 1 sibling respectively.

Those probabilities are: 0.20 and 0.65

So we get 0.20+0.65 = 0.85

There's an 85% chance of randomly picking someone who has fewer than two siblings.

she has insufficient time to complete her important tasks

hope this : )
