Given the discrete probability distribution above, determine the following:

(a) P(x>2)P(x>2) =

(b) P(x<5)P(x<5) =

(c) P(x≥4 or x<2)P(x≥4 or x<2) =

Answer 1

Answer #1

From given probability distribution above,

(a)

P(x > 2) = 0.2 + 0.1 + 0.4 = 0.7

(b)

P(x < 5) = 0.2 + 0.1 + 0.2 + 0.1 = 0.6

(c)

(x≥4 or x<2) = 0.2 + 0.1 + 0.4 = 0.7

One way consumers can evaluate alternatives is to identify important attributes and assess how purchase alternatives perform on those attributes. Consider the purchase of a tablet. Each attribute is given a weight to reflect its level of importance to that consumer. Then the consumer evaluates each alternative on each attribute (higher ratings indicate higher performance). A score can be calculated for each brand by multiplying the importance weight for each attribute by the brand's score on that attribute. These weighted...
