Question

a bag has 2 blue 3red and 5 yellow tilas. what is the probability of not picking a red tile

Answer 1

Answer:

0.2

Step-by-step explanation:

We have,

Number of blue tiles = 2

Number of red tiles = 3

Number of yellow tiles = 5

Total number of tiles = 2 + 3 + 5 is 10

Now, the probability of picking a blue tile is:

The number of blue tiles divided by the total number of tiles:

2 ÷ 10 = 0.2

Answer 2

Answer:

The probability is 70%, or 7/10.

Step-by-step explanation:

2 + 3 + 5 equals 10, which will be our denominator in this case.

Now, 10 - 3 equals 7, so the chances would be 7/10.

(Other Method):

2 blue + 5 yellow (excluding red) = 7 tiles

7 tiles / 10 tiles = 7/10.
