2*3 = 6 teaspoons per day per child
6*5 = 30 teaspoons 
30*3 = 90 teaspoons 
You need 90 teaspoons

1 teaspoon = 4.9289 mL
90*4.9289 = 443.6010 mL
443.6010 / 150 = 2.9573 bottles

You need at least 3 bottles

A bag contains 28 blue marbles and 12 red marbles. If Milton removes two marbles without replacing them, what is the probability
Ghella [55]

Answer:

A: 14/65

Step-by-step explanation:

Let A be the event of pulling a blue marble first, there are 28 blue marbles

Let B be the event of pulling a red marble second, there are 12 red marbles

There are 40 total marbles in the bag.

So

P(A) = 28/40

Since he pulls two marbles with out replacement, there is one less marble in the bag when he pulls the second marble, so there are only 39 marbles left, so

P(B) = 12/39

When calculating the probability of multiple events, you multiply their probabilities together, so we have

P(A then B) = (28/40)(12/39) = 336/1560

Now reduce the fraction...

112/520

28/130

14/65

Multiply the 3 by 16 and the 16 by 3 to even the numbers to 48.

then multiply the 2 above by 16 and the 3 above by 3 so it becomes like this

\frac{32}{48}  -  \frac{9}{48}  =  \frac{23}{48}
