Ajar contains 4 red marbles numbered 1 to 4 and 6 blue marbles numbered 1 to 6. a marble is drawn at random from the jar. find the probability of the given event.
(a) the marble is red then your answer is?
(b) the marble is odd numbered then your answer is?
(c) the marble is red or odd numbered then your answer is?
(d) the number is blue or even numbered then your answer is?

A. There are a total of ten marbles, with four being red, so answer is 4/10, or 2/5
B. The numbers are 1,2,3,4,1,2,3,4,5,6 and five are odd, so answer is 5/10, or 1/2
C. Combine the above answers (because it is either red or odd numbered), so answer is 9/10
D. There are six blue, so blue probability is 6/10, and even is five, so answer is 5/10, total answer is 11/10. This will definitely happen.
