A cup contains seven red erasers, four
yellow erasers, nine blue erasers, and five
green erasers. Samantha chose an eraser
at random, did not replace it, and chose
another. What is the probability that both
erasers chosen were blue?

Answers

Answer 1

Answer:

17/50

Plzzzz give me Brainliest!  

Answer 2

The probability that both erasers chosen were blue is 3/25.

To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.

There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.

To calculate the probability, we consider the events of choosing a blue eraser without replacement.

For the first pick, there are 9 blue erasers out of 25 total erasers.

After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.

The probability of choosing a blue eraser on the first pick is 9/25.

The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.

To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:

(9/25) * (8/24) = 72/600 = 6/50 = 3/25

Therefore, the probability that both erasers chosen were blue is 3/25.

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2.
Brian spent £39 that day.
Brian now had £4 less than Colin.
How much did they initially have altogether?

Answers

Answer:

£30

Step-by-step explanation:

Let Brian initially had money in his wallet = £x

and Colin had the money = £y

Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1

Therefore,  

⇒ x = 5y -------(1)

Brian spent £27 that day, so money left with him = £(x - 27)

After spending the money Brian had £3 less than Colin.

(x - 27) = (y - 3)

x = y + 27 - 3

x = y + 24 -------(2)

Now we equate the equations (1) and (2) for the value of x,

5y = y + 24

5y - y = 24

4y = 24

y = £6

From equation (2),

x = 6 + 24

x = £30

Therefore, Brian initially had £30.

now the right side

-8k+24-4k

combine like terms

-12k+24

so it'll look like this

-16k+24=-12k+24

add -12k to the left

-4k+24=24
