Answer 1

Answer:

Step-by-step explanation:

A flower shop has 5 yellow roses, 3 red roses and 2 white roses. Martin chooses 3 roses at random.  Draw up the probability distribution table for the number of white roses Martin chooses. Can someone please solve this question

Answer 2

Answer:

Step-by-step explanation:

Red Rose = 5

White Rose = x

Total Number of Rose = 5 + x

Probability of Red Rose = 5 / (5 +x)

Probability of White Rose = x / (5 +x)

Probability of White Rose/ Probability of Red Rose = 2 / 1

∴ [x / (5+x)] / [ 5 / (5+x)] = 2 /1

∴ x / 5 = 2

∴ x = 10

So there are 10 white roses.
