Answer: Our required probability is 0.56.

Step-by-step explanation:

Since we have given that

In urn I :

Number of red chips = 5

Number of white chips = 4

In urn 2 :

Number of red chips = 4

Number of white chips = 5

Two chips are drawn simultaneously from urn I and placed into urn II. Then a single chip is drawn from urn II.

Probability that the chip drawn from urn II is white is given by

P(E₁) = \dfrac{1}{2} = P(E₂)

P(W|E₁) = \dfrac{4}{9}

P(W|E₂) = \dfrac{5}{9}

So, by "Bayes theorem ", we get that

P(E_2|W)=\dfrac{0.5\times \dfrac{5}{9}}{0.5\times \dfrac{4}{9}+0.5\times \dfrac{5}{9}}\\\\P(E_2|W)=\dfrac{5}{9}=0.56

Hence, our required probability is 0.56.

On a lunch counter, there are 3 oranges, 5 apples, and 2 bananas. If 3 pieces of fruit are selected, find the probability that 1
muminat

Answer:

Probability = \frac{1}{24}

Step-by-step explanation:

Given

Oranges = 3

Apples = 5

Banana = 2

Total = 10

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

Probability = P(Orange) * P(Apple) * P(Banana)

Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}

<em>The difference in the numerator is as a result of picking the fruit without replacement</em>

Probability = \frac{30}{720}

Probability = \frac{1}{24}

1. I feel the need to explain things first before I write the numeric value. 
   Let x be the total number of students in the school. 25% of this value is given to be 35.
                        (0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.

2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52 
                              2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.
