Four couples at a party play a game. they decide to play in teams of two and select the teams randomly. all eight people write their names on slips of paper. the slips are mixed, then drawn two at a time. how likely is it that every person will be teamed with someone other than who he or she came with? run five trials using the random digits below. use the digits 0 and 1 for the first couple, 2 and 3 for the second couple, etc.
trial 1: 01, 71,02, 06,93, 04, 75, 51, 31, 51, 36
trial 2: 19, 67, 54, 49, 96, 20 08,71, 75, 31, 52
trial 3: 53, 38,75,23,01, 09, 11, 72, 74,38, 60
trial 4: 74,07,72,04, 60, 98, 45, 81, 46,99, 31
trial 5: 19, 36,67,98, 82, 58, 98, 53, 05,24, 08

step-by-step explanation:

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.
