Answer:

B. $\frac{1}{2}$

Step-by-step explanation:

We have been given a graph that shows the height of the 10 sunflowers grown in PJ's garden. We are asked to find the probability that the 11th flower will be at least 60 inches.

$\text{Probability}=\frac{\text{Total number of favorable outcomes}}{\text{total number of possible outcomes}}$

From the given experiment we can see that there are 5 sunflowers with height more than or equal to 60 inches, so total number of favorable outcomes is 5.

Since there are total 10 sunflowers, so total number of possible outcomes is 10. Upon substituting our given values in probability formula we will get,

$P(\text{The 11th plant will be at least 60 inches})=\frac{5}{10}$

$P(\text{The 11th plant will be at least 60 inches})=\frac{1}{2}$

Therefore, the probability that 11th plant will be at least 60 inches is $\frac{1}{2}$ and option B is the correct choice.

You have a bag full of apples. There are 8 Jonathan (red), 4 Granny Smith (green), and 5 Golden Delicious (yellow) apples in the

Answer:

Step-by-step explanation:

There are 8 Jonathan (red), 4 Granny Smith (green), and 5 Golden Delicious (yellow) apples in the bag.

a) Select 3 apples with replacement. Find the probability that all there are green.

Given that we are taking all apples with replacement, the probability of getting a green apples remains the same in all 3 trials. Therefore the probability here is computed as:

= (Number of green apples/Total apples)

= (4/17)^3

= 0.0130

Therefore 0.0130 is the required probability here.

b) Select 3 apples with replacement. Find the probability that none are red

Probability that none are red is computed here as:

= (Number of non red apples/Total apples)

= (9/17)^3

= 0.14838

Therefore 0.14838 is the required probability here

c) Select 4 apples with replacement. Find the probability that you get at least 2 red apples

Probability that we get at least 2 red apples when 4 apples are drawn is computed here as:

= 1 - (Probability that no red apple is taken out when 4 apples are taken out + Probability that 1 red apple is taken out when 4 apples are taken out)
