Ajar contains 12 red marbles numbered 1 to 12 and 4 blue marbles numbered 1 to 4. a marble is drawn at random from the jar. find the probability of the given event. (a) the marble is red your answer is : 3/4 preview (b) the marble is odd-numbered your answer is : 1/2 preview (c) the marble is red or odd-numbered your answer is : 7/8 preview (d) the marble is blue and even-numbered your answer is : 5/8

A jar contains 12 red marbles numbered 1 to 12

And 4 blue marbles numbered 1 to 4.

Total number of marbles = 12+4 =16

(a) A marble is drawn at random from the jar. The probability that the marble is red will be =

(b) In all, the odd number marbles are: 1,3,5,7,9,11 (in red) and 1,3(in blue) so total odd number marbles are = 8

So, probability that the marble is odd-numbered is :

(c) The probability that the marble is red or odd-numbered your answer is :

(d) The probability that the marble is blue and even-numbered =

what "following statement"?

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
