Question

A jar contains 8 red marbles numbered 1 to 8 and 9 blue marbles numbered 1 to 9. A marble is drawn at random from the jar. Find the probability that the marble is red or even-numbered

Answer 1

12/17

Explanation:

Number of red marbles: 8

Number of blue marbles: 9

Total number of marbles: 8 + 9 = 17

Number of red marbles: 8

Number of even-numbered blue marbles: 4

Total number of desired outcomes: 8 + 4 = 12

p(red or even-numbered) = 12/17
