Abox contains two coins: a regular coin and one two-headed coin. i choose a coin at random and toss it twice. define the following events. a= first toss results in a hb= second toss results in a hc= regular coin has been selectedare a and b independent? are a and b conditionally independent given c? find p(a|c), p(b|c), p(a∩b|c), p(a), p(b), and p(a∩b), and use them to answer the question.

answer: do we write it

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

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.
