Abox contains four red balls and eight black balls. two balls are randomly chosen from the box, and are not
replaced. let event b be choosing a black ball first and event r be choosing a red ball second.
what are the following probabilities?
p(b) =
p(
rb) =
p(bnr) =
the probability that the first ball chosen is black and the second ball chosen is red is about percent.

answer: i'm not sure

step-by-step explanation:

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
