Each tray has 5 colors, one color is purple, what fraction of the colors in 20 trays is purple

IrinaK [193]

Each tray is 1/5 purple. So one tray is 1/5 purple, and if you add another tray, you're adding the same amount of each color, so it's now 2/10 purple, which simplifies to 1/5. No matter how many you add, the fraction will be 1/5.

Marat540 [252]

Answer:

a. 0.75

b. 0.5526

c. 0.1974

Step-by-step explanation:

Probability is typically expressed as a fraction where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. In this case the suitable parts is the desired outcome and the total shipment is the total parts:

$\frac{suitable}{total}=\frac{15}{20}=\frac{3}{4}=0.75$

The probability the both the first and second part are suitable:

$\frac{15}{20}*\frac{14}{19}=\frac{210}{380}=0.5526$

Since the probability of getting a suitable part the first time is 15/20, then there is one less suitable part and one less part overall to choose on the second time, or 14/19.

Lastly, the probability of choosing a suitable part the first time is again 15/20, but the second part not being suitable would be 5/19:
