Respuesta :

Answer:

45%

Step-by-step explanation:

Here, we want to know the probability of a randomly selected yard having 6 or more than 6 trees

To get this, we simply add up the probability of 6 yards and above

That is the probability of 6, 8 , 10 and 12 yards

This is obtainable from the histogram

We then proceed to add up from the graph

What we have is;

0.05 + 0.25 + 0.10 + 0.05

= 0.10 + 0.10 + 0.25 = 0.45

This is same as 45/100 which is otherwise 45%

The probability that a randomly selected yard will have 6 or more trees is 45%.

Probability of having 0-2 tree = 0.35

Probability of having 2-4 tree = 0.20

Probability of having 4-6 tree = 0.05

Probability of having 6-8 tree = 0.20

Probability of having 8-10 tree = 0.10

Probability of having 10-12 tree = 0.05

What is the probability?

Probability is to quantify the possibilities or chances.

So, probability of having 6 or more trees

= (2*0.05 + 2*0.25 + 2*0.10 + 2*0.05)/(0.35*2+0.20*2+2*0.05 + 2*0.25 + 2*0.10 + 2*0.05)

=0.9/2

=0.45

=45%

So,  probability of having 6 or more trees =45%

Therefore, the probability that a randomly selected yard will have 6 or more trees is 45%.
