Prob(first ball being  blue) =  6 / (6 + 3 + 3) = 6/12 = 1/2
Prob ( picking a yellow ball) = 3 /12 = 1/4

As the 2 events are independent the probabilities are multiplied 
So the answer is 1/2 * 1/4 = 1/8

Flora used 1/5 of her flour to make some pies and 4/15 of it to bake some cakes. She also gave her friend 750g of flour. She had
MariettaO [177]

According to the information given, building and solving an expression, it is found that she used 1400 g of flour for the cakes.

<h3>How was the flour divided?</h3>
  • Her initial amount was of x.
  • She used \frac{x}{5} to make some pies.
  • She used \frac{4x}{15} to bake some cakes.
  • She gave her friend 750g, and had 850g left.

Hence, the <em>expression </em>is:

\frac{x}{5} + \frac{4x}{15} + 750 + 850 = x

x - \frac{x}{5} - \frac{4x}{15} = 1600

\frac{15x - 3x - 4x}{15} = 1600

8x = 15(1600)

x = 15(200)

x = 3000

For the cakes:

C = \frac{x}{5} + \frac{4x}{15} = \frac{3000}{5} + \frac{4(3000)}{15} = 600 + 800 = 1400

She used 1400 g of flour for the cakes.
