The state of Georgia has several statewide lottery options. One of the simpler ones is a "Pick 3" game in which you pick one of the 1000 three-digit numbers between 000 and 999. The lottery selects a three-digit number at random. With a bet of $1, you win $470 if your number is selected and nothing ($0) otherwise.

(a) With a single $1 bet, what is the probability that you win $470?

(b) Let X denote your winnings for a $1 bet, so x = $0 or x = $470. Construct the probability distribution for X. Use 3 decimal places.

X P(X)

$0 $470

(c) The mean of the distribution equals $

(d) Would this be considered a gain for you?

No. For every $1 I pay, I will lose $ 0.53 on average.

No. For every $1 I pay, I will lose $0.47 on average.

Yes. For every $1 I pay, I will win $0.47 on average.

(e) If you play "PICK 3" 100 times, how much should you expect to lose? $

IQ scores are normally distributed with a mean of 100 and standard deviation of 15. This implies a person with “average” intelligence scores 100 on an IQ Test. Various Psychological Classifications dub people with IQ scores of 130 as extremely intelligent or suggest they exhibit superior intelligence. What is the approximate probability that a random IQ test taker will score between 100 and 130?
