A landscaper is selecting two trees to plant. He has five to choose from. Three of the five are deciduous and two are evergreen.What is the probability that he chooses trees of two different types? Express your answer as a percent.
Answers
The probability that he chooses trees of two different types is 0.6 or 60%.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a landscaper who is selecting two trees to plant.
The total number of trees he has = 5
Total ways of choosing the two trees =
= 10
Total ways of choosing one of each =
= 6
So probability:
=
= 0.6 or 60%
Thus, the probability that he chooses trees of two different types is 0.6 or 60%.

Total ways of choosing one of each = 2*3 = 6
Probability = 6/10 = 0.6 = 60%

Answer:
a. Rational number 1.26
Simplest radical 3−√3
b. Simplest radical 28+10√3
Rational number 45.32
c. Rational number 89
Step-by-step explanation:
a. √3(√3-1)
To get the simplest radical
Apply the distributive property.
√3*√3-√3
Combine using the product rule for radicals.
√3*3+√3*−1
Move −1 to the left of √3.
√3*√3*3-1*√3
Multiply 3 by 3.
√9−1*√3
Rewrite 9 as 3^2
√3^2-1 *√3
Pull terms out from under the radical, assuming positive real numbers.
3−1*√3
Rewrite −1√3 as −√3.
3−√3
Rational number 1.26
b. (5+√3)²
Expand
(5+√3)²= 25 +5*√3+5*√3+3= 28 +10√3
Simplest radical 28+10√3
Rational number 45.32
c. (10+√11)(10-√11)
Expand
(10+√11)(10-√11)= 10*10+ 10*-√11+10*√11+√11*-√11
=100+ 10*-√11+10*√11- 11
=89- 10*√11+10*√11
=89
decreases
remains the same,

The probability that the randomly selected woman does not have red/ green color blindness is 0.9901.
What is Probability?
Probability can be simple defined as the chance of getting an outcome of an event which is likely. The sum of all the probabilities of outcomes of an event is always one.
Percentage of women who has red/ green color blindness = 0.99%
Suppose that a woman is randomly selected.
Probability of a woman having red/ green color blindness = 0.99/100
= 0.0099
We have total probability will be equal to 1.
Probability that the selected woman does not have red/ green color blindness = 1 - 0.0099
= 0.9901
In terms of percentage, 99.01% chance is there that the selected woman does not have red/ green color blindness.
Hence the probability that the woman does not have red/ green color blindness is 0.9901.
