The probability that a plant is edible is 4/5 and the probability that a plant grows at a constant rate and is edible is 14/19.

miskamm [114]

Answer: Probability that a plant grows at a constant rate, given it is edible is given by $\frac{35}{38}$ .

Step-by-step explanation:

Let B be an event that getting a plant grows at a constant rate.

Since we have given that

The probability that a plant is edible is given by

$P(A)=\frac{4}{5}$

The probability that a plant grows at a constant rate and is edible is given by

$P(A\cap B)=\frac{14}{19}$

We will use "Conditional probability ", i.e.

$P(A\mid B)=\frac{P(A\cap B)}{P(A)}$

$P(A\mid B)=\frac{\frac{14}{19}}{\frac{4}{5}}\\\\P(A\mid B)=\frac{14\times 5}{19\times 4}\\\\P(A\mid B)=\frac{70}{76}\\\\P(A\mid B)=\frac{35}{38}$

Hence, Probability that a plant grows at a constant rate, given it is edible is given by $\frac{35}{38}$ .

Sammy can paint the house by himself in 15 hours. With Nolan's help, it only takes 9 hours.

saw5 [17]

<u>Given</u>:

Sammy can paint the house by himself in 15 hours. With Nolan's help, it only takes 9 hours.

We need to determine the time it would take for Nolan to paint the house by himself.

<u>Time taken by Nolan:</u>

Let the rate that Sammy can paint the house by himself is $\frac{1}{15}$

The rate that Sammy and Nolan together paint the house is $\frac{1}{9}$

To determine the rate that it takes for Nolan to paint the house by himself is to subtract the rates.

Thus, we have;

$Rate=\frac{1}{9}-\frac{1}{15}$

$Rate=\frac{5-3}{45}$

$Rate=\frac{2}{45}$

Thus, the rate that it would take Nolan to paint the house by himself is $\frac{2}{45}$

The time that it takes for Nolan to paint the house by himself can be determined using the formula,

$Total \ houses=Rate \times Time$

Substituting the values, we have;

$1=\frac{2}{45} \times t$

$\frac{45}{2}=t$

$22.5=t$

Thus, Nolan takes 22.5 hours to paint the house by himself.
