5. Yesterday your friend made 1 gallon of dark pink paint using the information in the table.
Oxana [17]

Our friend's mistake when wanting to make a new mixture of pink paint is that she is only going to add 2 parts of white paint, the correct formula would be 3.

<h3>How to calculate how much paint you need to make 3 gallons of Pink paint?</h3>

To mix 3 gallons of pink paint we must take into account the following information:

  • 1 gallon of pink paint is equal to 3 parts red paint and 1 part white paint.

To find out how many parts we need to prepare 3 gallons of pink paint we must multiply the mix values for a gallon by 3.

Red paint:

  • 3 x 3 = 9

White paint:

  • 1 x 3 = 3

Based on the above, we need to use 3 parts white paint and 9 parts red paint to make 3 gallons of pink paint.

Note: This question is incomplete because the graph is missing. Here is the graph.

Find the missing probability. P(A)=7/20,P(A∪B)=191/400,P(A∩B)=49/400 ,P(B)=? A. 7/8 B. 1/4 C. 117/400 D. 19/40
spin [16.1K]

Answer:

B

Step-by-step explanation:

P(AUB)=P(A)+P(B)-P(A∩B)

191/400=7/20+P(B)-49/400

P(B)=191/400+49/400-7/20=240/400-7/20=12/20-7/20=5/20=1/4
