Answer:

a) P=0.24

b) P=0.31

c) Not independent.

Step-by-step explanation:

Incomplete question.

<em>a) What is the probability that a randomly selected order will be wrapped and sent to another person?</em>

P(W\&SOP)=P(SOP)*P(W|SOP)=0.30*0.60=0.24

W: wrapped

SOP: sent to other people

<em>b) What is the probability that a randomly selected order will be gift wrapped?</em>

P(W)=P(SOP)*P(W|SOP)+P(SR)*P(W|SR)\\\\P(W)=0.3*0.6+0.7*0.1=0.24+0.07=0.31

SR: sent to the right person

c) Is gift wrapping independent of the destination of the gift? Justify your response statistically.

To prove that they are independent, both of the following conditions must be met:

  • P(x|y) = P(x), for all values of X and Y.
  • P(x ∩ y) = P(x) * P(y), for all values of X and Y.

We start for the second condition.

P(W\cap SR)=0.1\\\\P(W)*P(SR)=0.31*0.7=0.217\\\\\\P(W\cap SR)\neq P(W)*P(SR)

This condition is not met, so the two variables are not independent.

Are the set of all square numbers under 50 and the set of all triangular numbers that are less than 50 disjoint?
Alina [70]

Answer:

No, the two sets are not disjoint.

Step-by-step explanation:

Set of triangular numbers to 50: 1, 3, 6, 10, 15, 21, 28, 36, 45

Set of square numbers to 50: 1, 4, 9, 16, 25, 36, 49

They have 1 and 36 in common, so they are not disjoint, or in other words, they have some of the same numbers.
