A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is not r
astraxan [27]

The probability of choosing two yellow marbles = 5/26

Step-by-step explanation:

Step 1 :

Given

Total number of marbles in the bag = 13 marbles

Number of yellow marbles = 6.

We choose 2 marbles from the bag without replacing and need to determine the probability that both are yellow.

Step 2 :

Probability of finding yellow marble in the first try = Number of yellow marbles / Total number of marbles = \frac{6}{13}

Once the yellow marble is selected we have 5 yellow marbles among 12 remaining marbles in the bag.

Probability of finding yellow marble in the second try = Number of yellow marbles / Total number of marbles = \frac{5}{12}

Step 3:

P(yellow in first 2 tries) = P(yellow in first try) * P(yellow in second try)

P(yellow in first 2 tries) = \frac{6}{13} * \frac{5}{12} = \frac{5}{26}

Step 4:

Answer:

The probability of choosing two yellow marbles = 5/26

How do you convert a mixed fraction to an improper fraction ?
maks197457 [2]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

a\frac{b}{c} ----> a mixed number

a is a integer

b/c < 1

so

a\frac{b}{c}=a+\frac{b}{c}

Adds the integer plus the fraction

\frac{ac+b}{c} ---> an improper fraction

\frac{ac+b}{c} > 1
