Alottery offers one $1000 prize, one $500 prize, and five $100 prizes. one thousand tickets are sold at $3 each. find the expected winnings and standard deviation if the double the winnings. and find the expected winnings and standard deviation if you play the game twice.

$1.98

Explanation:

The expected value is given by:

(prize amt - cost to play) x (probability of winning)

So, we have three prizesthe probability of winning the $1000 and $500 prizes is 1/1000 and the probability of the $100 prize is 5/1000. So we have:

(1000 - 3)(1/1000) + (500 - 3)(1/1000) + (100 - 3)(5/1000) ≈ $1.98

In theory, you should probably play.

if this a multiple choice question you are not listing any possible answers. so if it is, i will just name all types of plate boundaries.

convergent boundaries

transform boundaries

divergent boundaries

plate boundary zones
