Given P(A) = 0.072, P(B) = 0.180, and P(C) = 0.027, and that events A, B, and C are mutually exclusive, what is the P(A or B or
9966 [12]

Given P(A) = 0.072, P(B) = 0.180, and P(C) = 0.027, and that events A, B, and C are mutually exclusive,then P(A or B or C) is 0.279

<u>Solution: </u>

Given that probability of event A is P(A) = 0.072

Probability of event B is P(B) = 0.180

Probability of event C is P(C) = 0.027

Also event A, B and C are mutually exclusive.

Need to determine P( A or B or C )

For mutually exclusive events  

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

= 0.072 + 0.180 + 0.027  = 0.279

Hence probability of occurrence of event A or event B or event C , where A , B and C are mutually exclusive events is 0.279.

the lengths (in inches) of two sides of a regular pentagon are represented by the expressions 5x-27 and 2x-6. find the length of
fgiga [73]

Since the pentagon is regular, the sides are all of equal length. This tells you

... 5x-27 = 2x-6

... 3x = 21 . . . . . . . add 27-2x

... x = 7

The length of a side can be found by subtituting this value into either expression.

... 2·7-6 = 8 . . . . inches
