3. You are a senior consultant at a highly prestigious agency. You did a great job in 2020,

Anastasy [175]

Answer:

(a)The highest expected payout option 1

(b)1 and 3

(c)Option 1

Step-by-step explanation:

In this you just multiply the amount you are paid by chance if all are favorable to you, so in option 1 you would get $2,000 for each head you get on a flipped coin, so that would be 10*$2,000=$20,000 that's the highest paid, in the dice you get a maximum of 6 dots each, that would make $6,000*3=$18,000.

Rolling the dice can get you 5 scenarios where you don't get $6,000 when all three are lower than $6,000 which would be getting three 1's, two 1's and a 2, ot two 2's and a 1. That's why only option 3 and 1 are available for an almost certainity of getting $6,000

To know this you have to remember last problem, the getting $9,000 will never give you $16,000, and the dice would give you only 3 scenarios where you could end up winning $16,000 whihc would be getting all 6's, two 6's and a 5, or twop 5's and a 6, so your best option would be flipping the coin.

a town has 2 fire engines operating independently . the probability that a specific engine is available when needed is 0.96. wha

tester [92]

Answer:

The probability that neither is available when needed

$P(A n B)^{c} = 0.04$

Step-by-step explanation:

A town has 2 fire engines operating independently

Given data the probability that a specific engine is available when needed is 0.96.

Let A and B are the two events of two fire engines

given P(A and B) = 0.96 ( given two engines are independent events so you have to select A and B)

Independent events : P( A n B) = P(A) P(B)

The probability that neither is available when needed

$P(A n B)^{c} = 1- P(A n B)$

$P(A n B)^{c} = 1- 0.96 = 0.04$

Joanna joins a CD club. She pays $7 per month plus $10 for each CD that she orders. Write an inequality to find how many CDs she

Effectus [21]

Lets use x as the number of CD's that she will buy in a month. So knowing that, our inequality can look like this. 7 + 10x < or = 100. Why? because we will have to multiply 10 with the number of CDs she will purchase in a month to get the total she spends. Hence 10 times x. She also has to add a 7 membership fee per month to this. Also, she has to remember that what she paid has to be less or equal to 100 because the problem states that she spends no more than 100 a month.
