Two candy bowls contain red and green candies. the first bowl contains an even mix of red and green candies, while the second bowl contains 80% red and 20% green candies. a bowl is chosen, and a candy from that bowl is randomly selected. suppose that whenever a red candy is chosen, it came from the first bowl 50.0% of the time. what is the probability that the first bowl is chosen?

The probability that the first bowl is chosen is 0.38 = 38%.

Step-by-step explanation:

Number of bowls = 2

Probability of getting first bowl P(A)= 50%

Probability of getting second bowl P(B) = 100% - 50% = 50%

Percentage of red candies in first bowl P(R|A)= 50%

Percentage of green candies in first bowl P(G|A) = 50%

Percentage of red candies in second bowl P(R|B)= 80%

Percentage of green candies in second bowl P(G|B)= 20%

We have given that a red candy is chosen, so the probability that the first bowl is chosen.

Hence, the probability that the first bowl is chosen is 0.38 = 38%.

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.
