In a box of 200 batteries, 190 are good and 10 are defective. If 4 batteries are pulled from the box, what is the possible number of ways that 2 are defective? a. C(200, 2) x C(5, 2)

b. P(200, 2) x P(5, 2)

c. C(190, 2) x C(10, 2)

d. P(190, 2) x P(10, 2

step-by-step explanation:

what is the figure? attach a picture.

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.

i think it is c hope that
