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 =

it is 32.5

i hope i could u.
