You won 10 million dollars if your ticket exactly matches the 6 winning numbers. Otherwise you lose. There are no other prizes. A ticket costs $1. What is the expected value of this $1 ticket

The right answer is "1.6053".

Step-by-step explanation:

According to the question,

The expected value will be:

=

As we know,

The probability of winning the lottery will be:

=

So that, the expected value is:

=

=

=

it would be:

c.parallelogram.

answer:

step-by-step explanation:

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
