Abag contains 5 blue balls, 4 red balls, and 3 orange balls. if a ball is picked from the bag at random, what is the probability that it is a blue ball? answers have been rounded to the tenths place.

Hello there!

in the bag we have:

5 blue balls, 4 red balls, and 3 orange balls.

This adds up to 5 + 4 + 3 = 12 balls in total.

If we took a ball at random, the probability tath this ball is blue is equal to the quotient between the number of blue balls and the total number of balls.

this is P = 5/12 = 0.4166

now we need to round it to the tenths place, this is the first number after the decimal point, in this case, a 4.

To round it we need to see the number that is after if it is 5 or bigger we round up, if is smaller than 5 we round down. In this case, is a 1, means that we need to round down

p = 0.4

If a ball is picked from the bag at random, the probability that the ball taken was a blue ball, is equal to p = 0.4

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°
