Answer:
B) 2/9
Step-by-step explanation:
First, the probability of picking a red marble is 5/10, which is the same as 1/2. This is because there are 5 marbles in the bag that are red out of the 10 total marbles. Then, because we don't replace the marble, there are now 9 total marbles, with 1 blue, 1 white, 3 yellow, and 4 red. Now the probability of picking a red marble is 4/9.
Multiplying these two probabilities together gives you the probability of picking 2 red marbles in a row, which is 1/2 * 4/9 which is equal to 4/18, or 2/9 when simplified.

Answer:
8,4
Step-by-step explanation:
The answer I believe is 5 because 2 vases hold 10 red roses and 5 yellow roses. But since the person has 3 vases but it has to be the same amount as the first person. They would both have 30 flowers in their vases. But then each of the vases has 6 red roses so you just do 30 divided by 6 and you get 5.
