Question

Based on the data in this two-way table, if a flower is picked at random, what is the probability of getting a yellow flower?

Type of Flower/Color Red Pink Yellow Total
Rose 40 20 45 105
Hibiscus 80 40 90 210
Total 120 60 135 315

Answer 1

Answer 50:50

If you add 105 and 210 together you get 315 which is equal to the number of yellow flowers alone

Answer 2

Answer:
`(3)/(7)`

Explanation:

From the given table, the total number of flowers = 315

The total number of yellow flowers = 135

Then , if a flower is picked at random, the probability of getting a yellow flower is given by :-

`\text{P(Yellow)}=\frac{\text{Number of yellow flowers}}{\text{Total number of flowers}}\\\\\text{P(Yellow)}=(135)/(315)=(3)/(7)`

Therefore, the probability of getting a yellow flower is
`(3)/(7)`
