A container contains balls numbered from 1 through 55. A ball is drawn randomly and replaced. Then a second ball is drawn randomly. What is the probability that
the first ball is number 9 and the second ball is number 41?

A. 1/27 = 0.4%

B. 2/55 = 3.6%

C. 1/3,025 = 0.03%

D. 109/2,970 = 3.7%

E. 1/2,970= 0.33%

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
