Answer:
0.3125
Step-by-step explanation:
When a fair coin is tossed we find that
there are only two outcomes
Each toss is independent of the other
Hence if Xis no of heads then X is binomial with n = 5 and p = 0.5
Using binomial formula we can find probability for getting 3 heads exactly.
Required probability
= P(X=3)

The scale factor is 0.6. Then the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.
<h3>What is the scale factor?</h3>Scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
A scale model drawing of a garage is 6 centimeters wide and 9 centimeters long.
The scale model uses a scale in which 3 centimeters represent 1.8 meters.
The scale factor will be
m
Then the dimension of the actual garage will be
Length = 0.6 x 6 = 3.6 m
Width = 0.6 x 9 = 5.4 m
Then the area of the actual garage will be
Area of garage = Length x Width
Area of garage = 3.6 x 5.4
Area of garage = 19.44 m²
Thus, the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.
