joja [24]

Answer:1,0.5, or 0 it depends

Explanation:

The probability that one event occurred depends on the total of random event, being 1 the most of the probabilities

If the two marbles are blue the probability to select a marble blue is 1

If one of the marbles is blue and the other marble is of any color the probability to select the blue marbles is:

P=1 - 1/2=1/2

Being 1/2 or 0.5 the answer

If any of the marbles are blue then the probabilities are 0

Find area and perimeter

alisha [4.7K]

Answer:

Perimeter

P = P1+P2

P1 = 4a P2=2(a+b)

P1=4*5 P2=2(3+5)

P1=20 P2=2*8

P2=16

P = 20+16

P=36

Area

A=A1+A2

A1= $a^{2}$ A2=a*b

A1= $5^{2}$ A2=3*5

A1=25 A2=15

A=25+15

A=40

<h3>Step-by-step explanation:</h3>

Let that number be $n$ .

The quotient of a number and $6$ is $\frac{n}{6}\\$ .

"Increased" is just another term for "plus (+)" so $10$ increased by The quotient of a number and $6$ is $10 + \frac{n}{6}\\$

And it tells us that it is $15$ so it must be $10 +\frac{n}{6} = 15\\$
