Answer: $\bold{\dfrac{1}{4,}\qquad \dfrac{1}{2,}\qquad \dfrac{1}{8}}$

Step-by-step explanation:

Probability of an A out of A, B, C, D is: $\dfrac{1}{4}$

Probability of an odd (1, 3, 5) out of 1, 2, 3, 4, 5, 6 is: $\dfrac{3}{6}=\dfrac{1}{2}$

Probability of an A and an odd is: $\dfrac{1}{4}\times\dfrac{1}{2}=\dfrac{1}{8}$

the Wright flyer was the first successful powered aircraft a model was made to display in a museum with the length of 35 cm and

Savatey [412]

To compare the displayed Wright flyer in the museum with the actual plane, we have to compute for the ratio of the corresponding parameter. In this item, for both the display and the actual plane, we are given with the length. Computing for the ratio gives us,
ratio = length of the model / length of the actual plane

Length of the model = 35 cm
We need to calculate for the length of the model in ft.
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft

Going back to the equation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055

Hence, the dimensions used in the model is equal to 0.055 times the actual dimensions.

Error may occur because of the number of significant figures considered for rounding up or down of the answers after each calculation.
