19. a jar contains 1 purple, 2 red, 3 black, 1 yellow, and 3 orange marbles. if one marble is drawn at random, what is the probability of randomly drawing a marble that is not purple? a. 1% b. 9% c. 10% d. 90%

Answer

Explanation:

Step1: Calculate total marbles

$1 + 2+3 + 1+3=10$

Step2: Calculate non - purple marbles

$2 + 3+1 + 3=9$

Step3: Calculate probability

The probability $P=\frac{\text{Number of non - purple marbles}}{\text{Total number of marbles}}=\frac{9}{10}=0.9$ Converting to percentage, $0.9\times100% = 90%$

Answer:

D. 90%
