The tree is 19.55 meters tall.
Step-by-step explanation:
Shadow of tree = 20.7 meters
Height of tree = x
Hiker's shadow = 1.8 meters
Hiker's height = 1.7 meters
Using proportion
Shadow of tree : Height of tree :: Shadow of hiker : Height of hiker
Product of mean = Product of extreme
Dividing both sides by 1.8
The tree is 19.55 meters tall.

To find the probability of A or B, add the two probabilities (since they are mutually exclusive).
P(A)= 1/6 since 3 is one possibility out of 6
P(B)= 1/2 since there are 3 numbers that mke this true out of 6 and 3/6= 1/2
P(A or B)= 1/6+1/2
P(A or B)= 2/3
Final answer: 2/3
