you have a 50/50 chance the first time. but, as you ask for more times to get it the probability goes down. So you start out with a 1/2 chance, but after calculating the probability in the first two trails, it goes to a 1/4 probability

At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 10 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color? 10 over 40 multiplied by 9 over 39 10 over 40 multiplied by 10 over 39 10 over 40 plus 9 over 39 10 over 40 plus 10 over 39

10/40 * 9/39 This is because there are 40 boxes in total. The chance of a white box being handed out is 10/40. If a white box is handed out as a prize, there are going to be 39 boxes left, but only 9 of those 39 boxes would be white

Ivy has 4 tiles with pictures of plants and 5 tiles with pictures of animals. Ivy keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns another over tile without looking. What is the probability that the second tile that Ivy turns over has a plant on it? 37.5% 44.4% 60.0% 80.0%

ok, so you first started out with 9 tiles, but since she took one away you know have 8. plus since she took away that plant you now have a 3/8 chance of getting another plant, or a 37.5 chance

A box has 6 beads of the same size, but all are different colors. Tania draws a bead randomly from the box, notes its color, and then puts the bead back in the box. She repeats this 3 times. What is the probability that Tania would pick a yellow bead on the first draw, then a blue bead, and finally a yellow bead again? 1 over 216 1 over 36 1 over 6 1 over 2

1/6 because she never took any of the beads out so the probability never changes.
