In a statewide lottery, one can buy a ticket for $1. With probability .0000001, one wins a million dollars ($1,000,000), and wit

Dahasolnce [82]

Using the expected value, it is found that the mean of the distribution equals $0.1.

The expected value, which is the mean of the distribution, is given by <u>each outcome multiplied by it's probability</u>.

The probabilities of <u>each outcome</u> are:

.0000001 probability of earning $1,000,000.
.9999999 probability of earning $0.

Thus, the mean is given by:

$E(Y) = 0.0000001(1000000) + 0.9999999(0) = 0.1$

Thus showing that the expected value is $0.1.

Need a refresh on scientific notation? help.

Dmitrij [34]

Scientific notation can be scary but it really is simple
the exponent after the 10 is how many places you move the decimal. If it is positive you move it right, if it negative you move it left
2 x 10^2 means you move the decimal place right twice to make 200
4 x 10^-3 means you move the decimal place left three times to make .004
The question is asking you to multiply 900000 and .0000006
