A homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bed
cestrela7 [59]

Answer:

0.97

Step-by-step explanation:

Given that a homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bedroom (above the kitchen). If cooking produces smoke in the kitchen, the probability of setting off the dining room alarm (D) is .95. The probability of setting off the bedroom alarm (B) is .40.

Both alarms are independent of each other.

Probability for smoke detection=P(any one alarm rings)

=P(Kitchen alarm sets off)+P(bed room alarm sets off)-P(Both sets off)

Since both are independent

P(Both) = 0.95*0.40\\=0.38

Probability for smoke detection

= 0.95+0.40-0.38

=0.97

What do you think are some of the advantages and disadvantages of a capitalist economic system? Do you feel that the advantages
Tcecarenko [31]
Hello!

Advantages of a capitalist economic system:

• Economic growing and expansion.

• Consumer choice (The consumers get to choose what to consume, which leads to better products and services).

• Efficiency of economics (Goods and services based on demand)



Disadvantages of a capitalist economic system:

• Inequality (A small group of people hold most of the wealth)

• There can be a monopoly of power (a specific enterprise is the only supplier of particular commodity)

• Unemployment

• Social benefit ignored. A free market will ignore externalities.

No, I feel the disadvantages outweigh the advantages, because there are more of them.
