Step-by-step explanation:
Total bulbs = 80
Probability of defective bulbs = 45/80 = 9/16
Probability of non warranty bulbs = 32/80 = 4/5
1/9 or 1/3 hope this helps!
Should be C. 1/19. because if there's 20 maebles in the bag and without replacing the marble then it actually would be 2/18
8 / 2 = 45 / x....8 servings to 2 cups = 45 servings to x cups
cross multiply
(8)(x) = (2)(45)
8x = 90
x = 90/8
x = 11 1/4 (or 11.25) cups of flour are needed <==
