Question

Fiona has to choose a bouquet for her wedding. There is a 98% chance she will use red roses, an 87% chance she will use orchids and a 94% chance she will use Gerber daisies. Given that the probability she has both roses and orchids is 0.82, the probability she has both Gerber daisies and roses is 0.97, what is the probability she has Gerber daisies as she has already chosen red roses?

Answer 1

0.99=0.97/0.98 roses and daisies divided by roses

Answer 2

Answer: 0.99

Explanation:

Chance she will use red roses: 98%

Chance she will use orchids: 87%

Chance she will use Gerber daisies: 94%

probability she has both roses and orchids: 0.82

Probability she has both Gerber daisies and roses: 0.97

What is the probability she has Gerber daisies as she has already chosen red roses =?

Probability of having daisies and choosing red roses= Probability of Daisies and roses/ Probability of red roses)

0.97/0.98 = 0.99
