Answer:
t = -1
Step-by-step explanation:
15(t+2)+9t=6
15t + 30 + 9t = 6
combine like terms
24t +30 = 6
subtract 30 both sides
24t = -24
t = -1
22-5(6v-1) = -63
22- 30v + 5 = -63
27 -30v = -63
subtract both sides by 27
-30v = -90
divide it by -30
v = 3
Answer:
Given two events A and B of a sample set :-
P[A] = 0.20
P[not B]=0.40
To find P[A or B]:
......[1]
Calculate for and
P[B] = 1- P[not B]
Substitute the value P[not B] we get;
P[B] = 1-0.40 = 0.60
Substitute the given values we get;
Then;
Therefore, the value of P[A or B] is, 0.75.
