Answer:

The answer is below

Step-by-step explanation:

A store carries four brands of DVD​ players, J,​ G, P and S. From past​ records, the manager found that the relative frequency of brand choice among customers varied. Using the given probability values for each of the four​ brands, find the probability that a random customer will choose brand J or brand P.

P(J)=0.22​, ​P(G)=0.18​, ​P(P)=0.35​, ​P(S)=0.25

Answer: Probability is the ration of possible outcomes to the total number of possible outcomes. The probability of mutually exclusive events i.e. events that cannot occur at the same time is the sum of their individual probabilities. If two events A and B are mutually exclusive events, then:

P(A or B) = P(A) + P(B)

Given that P(J)=0.22​, ​P(G)=0.18​, ​P(P)=0.35​, ​P(S)=0.25, the probability that a random customer will choose brand J or brand P is given by:

P(J or P) = P(J) + P(P) = 0.22 + 0.35 = 0.57

Pls can someone help me and have it right
dangina [55]

Answer:

Problem 1:

a. x=2

b. x=3

c. x=1

Problem 2:

A multiplication equation to hold the table true:

18\times3=54

A division equation to hold the table true:

\frac{54}{3} =18

Step-by-step explanation:

Given in problem 1:

(a). The equation is \frac{x}{6} > 1

It holds true for all values of x> 6.

Let us say x=12,

\frac{x}{6}=\frac{12}{6}  =2 which is greater than 1.

(b). The equation is \frac{x}{6} < 1

It holds true for all values of x< 6.

Let us say x=3

\frac{x}{6} =\frac{3}{6} =\frac{1}{2} which is less than 1.

(c). The equation is \frac{x}{6} = 1

It holds true for only x= 6.

Let us say x=6,

\frac{x}{6} =\frac{6}{6}=1 which is equal to 1.

Problem 2:

A multiplication equation to hold the table true:

18\times3=54

A division equation to hold the table true:

\frac{54}{3} =18

Therefore these are the values which hold true to the equation in problem 1 and 2.
