A box contains 14 large marbles and 10 small marbles. Each marble is either green or white 8 of the large marbles are green, and
netineya [11]

The probability that the marble is large or white is 0.5714.

<h3>What is probability?</h3>

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

Probability of an event is

P(A) = Number of favorable outcomes/ Total Number of outcomes      

       = n(A)/n(S)

where

P(A) is the probability of an event “A”

n(A) is the number of favorable outcomes

n(S) is the total number of events in the sample space.

We have,

Number of large marbles = 14

Number of small marbles = 10

Number of large green marbles = 8 which implies

Number of large white marbles = 14 - 8 = 6

Number of small white marbles = 4 which implies

Number of small green marbles = 10 - 4 = 6.

Now, let

Let X be the event of drawing large marble.

Let Y be the event of drawing small marble.

Let M be the event of drawing white marbles.

Let N be the event of drawing green marbles.

Since only one marble is drawn at a time ,

so P(X) =  14/24

    P(Y) = 10/24

    P(M) = 10/24

    P(N) = 14/24

We have to find the probability that a marble is large or white i.e. P(X∪M).

P(X∪M) = P(X) + P(Y) - P(X∩M)

P(X∩M) = In 14 large marbles 6 are white marbles = 6/14.

P(X∪M) = P(X) + P(Y) - P(X∩M) = 14/24 + 10/24 - 6/14 = 0.5833+0.4167-0.4286 = 0.5714.

Therefore, the probability of drawing large or white marble is 0.5714.

One number is 7 more than another number. the sum of the numbers is 63. what are the numbers?
worty [1.4K]
Let the smaller number be x
x+x+7=63
2x+7=63
2x=56
x=28

28+7=35

The two numbers are 28 and 35

X+ 3/4 ≥ -1/3<br> Can I get help with this I need the work and answer.
andreev551 [17]
Solving this inequality is similar to solving a regular equation. The only thing you need to worry about with inequalities is that when you are dividing or multiplying by a negative number, you must flip the inequality sign. You won't have to worry about that here!

You are told x + 3/4 ≥ -1/3. Isolate the x by subtracting 3/4 from both sides. To subtract fractions, find a common denominator on both fractions, subtract the numerators, put the difference over the common denominator, and simplify if needed. The common denominator between \frac{3}{4} and - \frac{1}{3} is 12.
1) To make the denominator of \frac{3}{4}, 12, multiply it by 3/3 (aka 1):
\frac{3}{4} \times  \frac{3}{3} =  \frac{9}{12}

2) To make the denominator of - \frac{1}{3}, 12, multiply it by 4/4:
- \frac{1}{3} \times \frac{4}{4} = -\frac{4}{12}

3) Subtract the fractions to find the inequality for x:
x + \frac{3}{4}  \geq - \frac{1}{3}\\&#10;x + \frac{9}{12}  \geq -\frac{4}{12}\\&#10;x  \geq -\frac{4}{12} - \frac{9}{12} \\&#10;x  \geq  -\frac{13}{12}

You answer is x ≥ -13/12, or if you want to make -13/12 a mixed number, x ≥ -1 \frac{1}{12}.
