A bag contains 10 blue marbles, 7 white marbles, 6 red marbles, and 2 Green marbles. what is the probability of randomly selecting the blue marble?

Step-by-step explanation:

Number of blue marbles = 10

Number of white marbles = 7

Number of Red marbles = 6

Number of Green marbles = 2

Total marbles = 10 + 7 + 6 + 2 = 25

Probability of selecting the blue marble = 10/25 = 2/5

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
