Identify the pair of events as dependent or independent. a member of the junior class and a second member of the same class are randomly selected.

It is considered as dependent events.

Step-by-step explanation:

Since we have given that

A member of the junior class and a second of the same class are randomly selected.

Then both the events are dependent events.

Because we know the definition of dependent events which states that dependent events are those events if occurrence of one event gets affected by occurrence of another event.

As choosing the second member is completely dependent upon choosing the first member.

Number of possible outcome of choosing second member would reduce by 1 member.

So, it is considered as dependent events.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
