Question

Emma has a collection of red and pink roses. She can add any one rose to her vase. She is unable to decide which rose to select, so she decides to roll a standard die. If the outcome is an even number, then Emma will select a red rose. If the outcome is an odd number, then she will select a pink rose. What is the probability that a pink rose is added into the vase?

Answer 1

Answer:

3/5

Step-by-step explanation:

odd numbers in a standard dice is : 1, 3,5.

therefore there are 3 out of 6 possibilities of it being pink rose.

Answer 2

Answer: $\frac{1}{2}$

Step-by-step explanation:

Since she is rolling a standard die , a standard has 6 faces , that is

{ 1 , 2 , 3 , 4 , 5 , 6 }

And it was said that if the outcome on the die is an even number , Emma will select a red rose and if the outcome is odd she will select pink rose.

Therefore , the probability of adding a pink rose will be :

P( pink ) = number of odd number / total number

The odd numbers are : { 1 , 3 , 5 }

Therefore , P ( pink ) = 3/6 = 1/2
