Answer 6

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

Answer 10

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

Answer 11

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

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%

@ccswims

Answer 22

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
