What is the probability that he chooses trees of two different types? Express your answer as a percent.

Answer 1

Answer 2

No

Answer 3

im guessing u r suppose to use where they said the thing about the 3 and the 5 part as your percentage?

Answer 4

Like i dont get it ? Wym

Answer 5

Total number of combinations of 2 from 5 is 5C2 = (5*4)/(2*1)

Hint: There are 2 ways he can pick one evergreen and 3 ways he can pick a deciduous.

Answer 6

So after you multiply you divide 20/2 right?

Answer 7

And it will be 10 ?

Answer 8

yes 10 is all the possible combinations of 2 trees out of 5

and possible wyas to pick 2 different trees = 3*2 = 6

Answer 9

So the answer would be 10 or 6?

Answer 10

so required probability = number of possible ways to get different trees / total ways to pick 2

multiply this by 100 to convert to percentage.

Answer 11

That would be 6 and 10?

Answer 12

6 divided by 10

Answer 13

60?

Answer 14

60% yes
