Outcome A B C D Probability 0.5 0.3 ? ? What is the probability of the outcome (A or B)? a. 0.3 c. 0.8 b. 0.5 d. 0.15 Please select the best answer from the choices provided A B C D

0.8

Step-by-step explanation:

Given :

Outcome - - - - A - - - - - B - - - - - C - - - - - D

Probability - - 0.5 - - - 0.3 - - - - - -? - - - - -?

Probability of the outcome (A or B) :

(A or B) is the union of two outcomes, that is union of outcome A with the the outcome of B. Usually interpreted as containing elements of both A and B.

The probability denoted as (A or B) of two different outcomes is the sum of the individual probability of A and probability of B

Therefore,

(A or B) = 0.5 + 0.3 = 0.8

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
