A bag has 5 red marbles, 6 blue marbles and 4 black marbles
so total no. of marbles = 5 + 6 + 4 = 15
now probability of picking a black marble = 4/15
after replacement again probability of picking black marble is 4/15
it is given that black marble is picked two times
so probability of picking black marble two times or picking , replacing , and then picking is 4/15*4/15 = 16/225
Given:
Width = 2 ft
Parallel bases: 4 ft and 6 ft.
The area is (1/2)(Sum of the bases) x Width.
Therefore the area is
A = (1/2)*(4 + 6)*2
= (1/2)*10*2
= 10 ft²
Answer: 10 ft²
Answer: The bacony floor is 37 feet above the ground floor.
Step-by-step explanation:
Here, the ground level is marked as 0 feet.
The elevation of the balcony floor is 37 feet.
The elevation of the basement floor is -17 feet.
Since elevations relative to ground level at 0 feet.
i.e. elevation of balcony floor is same as the distance of balcony floor from ground.
That means the bacony floor is 37 feet above the ground floor.
Hence, the bacony floor is 37 feet above the ground floor.
