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
Answer:
5
Step-by-step explanation:
Factors of 35: 1,5,7,35
Factors of 10: 1,2,5,10
5 is the greatest common factor.
Assuming that we are solving in terms of n.
Start by distributing:
2(n + 5)
(2*n) + (5*2)
2n + 10 = -2
Subtract 10 to start toward isolating your variable:
2n = -12
Divide by two to finish solving:
n = -6
