Suppose that 66% of people own dogs. if you pick two people at random, what is the probability that they both own a dog?

probability of one person owning a dog = 0.66

probability of picking 2 people who own dogs  = 0.66 x 0.66 = 0.4356

Round answer as needed.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

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°
