Two numbers are randomly selected on a number line numbered from 1 to 9. Match each scenario to its probability.
the probability that both numbers
are greater than 6 if the same
number can be chosen twice
the probability that both numbers
are less than 7 if the same
number can be chosen twice
the probability that both numbers
are odd numbers less than 6 if the
same numbers cannot be chosen
twice
the probability that both numbers
are even numbers if the same
numbers cannot be chosen twice

1/9; 4/9; 1/12; 1/6

Step-by-step explanation:

the probability that both numbers are greater than 6 if the same number can be chosen twice--> 3/9 * 3/9 = 1/9

the probability that both numbers are less than 7 if the same number can be chosen twice --> 6/9 * 6/9 = 4/9

the probability that both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice --> 3/9 * 2/8 = 1/12

the probability that both numbers are even numbers if the same numbers cannot be chosen twice --> 4/9 * 3/8 = 1/6

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
