Sveta_85 [38]3 years ago
4 0

Answer:

<em>32 units² </em>

Step-by-step explanation:

A_{1} = 4(2 + 2 + 6) ÷ 2 = 20

A_{2} = (2 × 2) ÷ 2 = 2

A_{3} = 2² = 4

A_{4} = 2 × 6 ÷ 2 = 6

A = A_{1} + A_{2} + A_{3} + A_{4} = <em>32 units²</em>

You buy a lottery ticket to a lottery that costs $10 per ticket. There are only 100 tickets available to be sold in this lottery
riadik2000 [5.3K]

Answer:

Loss of $1.20

Step-by-step explanation:

The possible outcomes for this lottery and their probabilities are:

- a 1 in 100 chance of winning $450

- a 2 in 100 chance of winning $120

- a 4 in 100 chance of winning $30

- a 93 in 100 chance of losing $10

Therefore, the expected value of this lottery when buying one ticket is:

E(X) = \frac{1}{100}*\$450+ \frac{2}{100}*\$120+ \frac{4}{100}*\$30-\frac{93}{100}*\$10 \\E(X) = -\$1.2

Therefore, you are expected to lose $1.2 per ticket.
