Question

Tim has 51 tiles mixed together in one bag.

13 are green, 23 are white and 15 are yellow.
Tim picks tiles randomly from the bag one at a time and fixes them to the wall.
The first tile he chooses is green.
What is the probability that the second tile he chooses will be yellow?
Express your answer as a percentage.

Answer 1

30%.

Explanation:

After picking the green one there are 50 tiles left in the bag.

Probability the second is yellow = number of yellow tiles / 50

= 15/50

= 3/10

= 30%.

Answer 2

30% will be yellow

Explanation:

13 green

23 white

15 yellow

51 in all

1 green tile is chosen

50 tiles left in all

Probability of yellow.

15 out of 50 = 15/50 = 3/10 = 0.3

To percentage.

0.3 × 100 = 30

30 add %

30%
