Answer:
9
Step-by-step explanation:
Let us say, Olivia's age is x.
Now as the question says, we will get this equation.

Multiply both sides by 3.

Collect like terms.

Calculate.

Divide both sides of the equation by -5.

Then, we will get the answer.
<u>I</u><u> </u><u>h</u><u>o</u><u>p</u><u>e</u><u> </u><u>i</u><u>t</u><u> </u><u>h</u><u>e</u><u>l</u><u>p</u><u>s</u><u>.</u>
To answer problems like this you have to use binomial:
P (x > 1) = 1 – p (0
< x < 1) > .7
So:
1 – p (0) – p (1) >
.7
1 – (3/ 4) ^n – (3/ 4)
^n (n – 1 ) (1/ 4) > .7
Therefore n > 5.185,
and the smallest value of n so that we can satisfy the given condition is 6
