Answer 1

Answer:

[tex]P(Joe) = 0.3[/tex]

[tex]P(Joe\ \&\ North\ Side) = 0.2[/tex]

Explanation:

Solving (a): P(Joe)

To get this probability, we simply add up the items in the column named Joe.

These items are:

Joe: 34 and 70

And the total is:

[tex]Joe = 34 + 70[/tex]

[tex]Joe = 104[/tex]

The overall population of the system is:

[tex]Total = 409[/tex]

So:

[tex]P(Joe) = \frac{Joe}{Total}[/tex]

[tex]P(Joe) = \frac{104}{409}[/tex]

[tex]P(Joe) = 0.3[/tex]

Solving (a): P(Joe and North Side)

To get this probability, we simply get the intersecting element of Joe column and North Side row.

From the table, the intersecting element is:

Joe and North Side: 70

The overall population of the system is:

[tex]Total = 409[/tex]

[tex]P(Joe\ \&\ North\ Side) = \frac{Joe\ \&\ North\ Side}{Total}[/tex]

[tex]P(Joe\ \&\ North\ Side) = \frac{70}{409}[/tex]

[tex]P(Joe\ \&\ North\ Side) = 0.2[/tex]
