Answer:

11/25 The right answer is not a part of the options given.

Step-by-step explanation:

Given;

Probability that event M will not occur = 0.8

Probability that event R will not occur = 0.6

Then the ;

Probability that event M will occur = 1 - 0.8 = 0.2

Probability that event R will occur = 1 - 0.6 = 0.4

If events M and R cannot both occur, probability that either event M or event R will occur

=  probability that M occurs and R does not or the probability that R occurs and M does not

= 0.2 × 0.6 + 0.4 × 0.8

= 0.12 + 0.32

= 0.44

= 11/25

How do you find a linear equation
Tasya [4]
Flip equation
- 12x + 96 = y - 11
add -96 to both sides
- 12x + 96 +  - 96  =   \\ y - 11  +  - 96 - 12x = y - 107
divide both sides by -12
\frac{ - 12x}{12}  =  \frac{y - 107}{12}
ANSWER
\frac{ - 1}{12} y +  \frac{107}{12}
