P(Y1 | R2) = P(Y1R2)/P(R2)

P(R2 | Y1) = 4/9 ..........P(Y1) = 1/3
P(R2 | B1) = 1/2 ..........P(B1) = 2/9
P(R2 | R1) = 3/8 ..........P(R1) =4/9

P(R2) = [4/9*1/3] + [1/2*2/9] + 3/8*4/9] = 23/54

P(Y1R2) = P(Y1)*P(R2|Y1) = 1/3*4/9 = 4/27
P(Y1 | R2) = 4/27*54/23 =8/23

hope this help

olasank [31]

Answer:

B) 4 tablespoons of salt

Step-by-step explanation:

Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?

Given is the ratio of salt and beans to make recipe for 1 liter of beans.

Ratio given for 1 liters of beans; \frac{salt}{beans} = \frac{\frac{1}{3} }{\frac{1}{4} }.

Now, simplifying the ratio

\frac{\frac{1}{3} }{\frac{1}{4} }= \frac{1}{3} \times \frac{4}{1}

∴ Ratio for salt and bean in a recipe for 1 liter of beans is \frac{4}{3}.

Next, finding the proportion of salt to make triple the recipe.

Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.

∴ The proportion of salt in 3 liter beans= \frac{4\ tablespoon\ salt}{3\ tablespoon\ beans} \times 3\ lts\ of\ beans

Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.
