To solve both of these expressions, we want to add or subtract from left to right.

For the first one, we can rewrite it as:

8-6-9
=2-9
=-7

The second one we can rewrite as:

5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11

Answer:

A. P(EC) = 0.4

B. P(E∪E) = 0.75

C. P(EC ∩ FC) = 0.25

Step-by-step explanation:

Let us calculate -:

we are given with - P(E) = 60 and P(F) =.15,

Thus , (a) $P(E^C)=1-P(E)$

$=1-0.6$

$=0.4$

(b) P(E∪F) = P(E) + P(F)

= 0.60 + 0.15

= 0.75

$=1-0.75$

= $0.25$

Hence , the answers are -A. P(EC) = 0.4 , B. P(E∪E) = 0.75 , C. P(EC ∩ FC) = 0.25.
