There is a bag filled with 6 blue and 5 red marbles.
adelina 88 [10]

Answer:

0.5041 = 50.41% probability of getting 2 of the same colour

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability of getting 2 of the same colour?

Both blue or both red

Since they are replaced, we have, in each trial:

6 blue from a set of 6 + 5 = 11

5 red from a set of 6 + 5 = 11

Probability of both blue:

Each with 6/11 probability. So

P = (\frac{6}{11})^2 = \frac{36}{121}

Probability of both red:

Each with 5/11 probability. So

P = (\frac{5}{11})^2 = \frac{25}{121}

Total:

p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041

0.5041 = 50.41% probability of getting 2 of the same colour

Luden [163]

Answer:  4/7

<u>Step-by-step explanation:</u>

the number of chairs = 7

the number of cushions = 11

Every chair has at least 1 cushion. There are 7 chairs so 7 cushions are used.

There is a total of 11 cushions and 7 cushions are already distributed to the chairs so there are 4 chairs with a 2nd cushion.

Chairs with 2 cushions ÷ Total chairs = 4/7

Lucy is tiling her bathroom. She buys white and blue tiles in the ratio 13:2.Blue tiles cost £2.80 while white tiles cost £2.35.
krok68 [10]

Answer:

* Lucy spent £289.2 on tiles *

Step-by-step explanation:

We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -

\frac{13}{2} = \frac{x}{16} ... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,

13 * 16 = 2x,

208 = 2x,

x = 104 white tiles

So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,

£2.80 * 16 = £44.8,

£2.35 * 104 = £244.4,

Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
