Use formula for theoretical probability:

Pr=\dfrac{\text{the number of favorable outcomes}}{\text{the number of possible outcomes}}.

1. The probability that Jonas will get an orange is

Pr(\text{Jonas gets orange})=\dfrac{5}{13}.

2. Ben is taking a piece second and he has 12 piecies left, among them 5 apples, 4 oranges and 3 bananas. The probability that Ben will get an apple is

Pr(\text{Ben gets apple})=\dfrac{5}{12}.

3. Use the product rule to determine

Pr(\text{Jonas gets orange and Ben gets apple})=\dfrac{5}{13}\cdot \dfrac{5}{12}=\dfrac{25}{156}.

Answer: correct choice is A.

Hoochie [10]

Answer:

We have been given an equation x^2+9x+20=0

We will factorize it by  middle term splitting.

Step 1: x^2+5x+4x+20=0

Taking common factors out by clubing first two terms ad last two terms

Step 2: x(x+5)+4(x+5)=0

Step 3: (x+4)(x+5)=0

Equating both above factors to zero as:

Step 4: (x+4)=0\Rightarrow x=-4

   And (x+5)=0\Rightarrow x=-5.
