Answer 2

Find the probability that a randomly chosen tree will be a `California redwood tree taller than 300 ft.`

Answer 3

B !

Answer 4

25/305

Answer 5

think again

Answer 6

how many total trees are there ?

Answer 7

It is, D Because you do 25 / 601. Since it asks for the probability of a randomly chosen tree from the total amount of trees.

Answer 8

25/ 60

Answer 9

so it's C ? @ganeshie8

Answer 10

out of total amount of trees both over 300 and under 300

Answer 11

Ohh I mean D 25/610

Answer 12

yes, good job!
