A bag has 5 white marbles, 8 red marbles, and 4 purple marbles. If we take a marble randomly, then what is the probability of not getting purple marble?
Answer & explanation
Correct answer: option 4
Total marbles = 4+8+5= 17 Purple marbles = 4
Not getting purple marble i.e getting only white or red marbles
⇒ P(not getting purple marble) = $\frac{\text{getting only white or red marbles}}{\text{Total number of marbles}}$ = 13/17
