Agumball machine has 2 red gumballs and 2 green ones. if you buy 2 gumballs, what is the probability that both of them will be red?

so there are 4 gumballs altogether, so if you were to buy 2 you would have a half/half chance. 2/4, 1/2. Hopefully I did this right.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
