Answer: The expected loss is $2.3

Explanation:

Total number of tickets to be sold = 100 tickets

one $450 prize, the expected gain = 450 x (1/100)  = $4.5

two $110 prizes, the expected gain = 110 x (2/100) = $2.2

four $25 prizes. the expected gain = 25 x (4/100) = $1

Expected gain (loss) = Total expected gain - Cost of the ticket

                                  = (4.5 + 2.2 + 1 ) - 10

                                  = (2.3)

The expected loss is $2.3

Answer:

$2.3

Explanation:

cost per ticket = $10

Total number of tickets to be sold = 100 tickets

since there are 100 tickets the probability that you would win any of the prize would be:

For the one(1)  $450 prize

 expected gain = 450 x (1/100)  = $4.5

For the two(2) $110 prizes

expected gain = 110 x (2/100) = $2.2

For the four(4) $25 prizes.

 expected gain = 25 x (4/100) = $1

Expected gain (loss) = Total expected gain - Cost of the ticket

= (4.5 + 2.2 + 1 ) - 10 = - 2.3

The expected loss is $2.3

inessss [21]

A group of creatures that are extremely rare, scarce, or infrequently encountered is referred to as a rare species.

Even though extinctions happen naturally, the pace of plant and animal extinctions today is substantially higher than it was previously. The main factor contributing to greater extinction rates is habitat loss.

The introduction of harmful nonnative species, pollution, disease transmission, and habitat changes are some additional causes. Overexploitation of wildlife for commercial gain is another. Species that are in risk of going extinct include those plants and animals that have become so scarce.

Animals and plants that are threatened with extinction across all or a sizable portion of their range are those that are very likely to do so in the near future. The most species are in danger from overuse of natural resources, such as overfishing, overhunting, and deforestation of forests. The extension of land for agriculture, cattle, wood, and aquaculture is another significant industry in the world.
