Answer:
Option C is correct
P(A or B) = 0.65
Step-by-step explanation:
<u>Given:
</u>
P(A) =0.5
P(B)=0.30
P(A and B) =0.15
( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)
<u>Solution:</u>
To find the probability of the Happening of event A either event B we will use the following formula
P(A or B) = P(A) + P(B)-P(A and B)
= 0.5 + 0.3 - 0.15
=0.65

Answer:
3.6
Step-by-step explanation:
6r-5 = -3(r-2)
6r-5 = -3r+6
6r-3r = 3r
6+5 = 11
11/3 = 3.6
Answer:
-17
Step-by-step explanation:
-2(3) = -6
-6(3) = -18
3(3) = 9
-18+9 = -9
-9 - 8 = -17
