I believe this has to do with theoretical and experimental probabilities.

Experimental probabilities are what actually happens and theoretical probabilities are what is expected to happen.

A coin landing on tails 8 out of 10 times....this is experimental probability
results based on an experiment....this is experimental probability
outcomes that should happen....this is theoretical probability
rolling a sum of 9 in 5 trials....this is experimental probability

so the one that is the odd ball is : outcomes that should happen

Answer: x=45

<u>Simplify both sides of the equation</u>

<u></u>x+1.2x+1=100

(x+1.2x)+(1)=100 (Combine Like Terms)

2.2x+1=100

<u>Subtract 1 from both sides</u>

<u></u>2.2x+1-1=100-1\\2.2x=99<u></u>

<u></u>

<u>Divide both sides by 2.2</u>

<u></u>2.2x/2.2=99/2.2<u></u>

<u></u>x=45<u></u>
