It would be 2.1×10 to the power of 13
<span>3 4/9 + 5 1/3
= 3 4/9 + 5 3/9
= 8 7/9
11 1/5 + 2 1/2
= 11 2/10 + 2 5/10
= 13 7/10
7 4/5 + 1 9/10
= 7 8/10 + 1 9/10
= 8 17/10
= 9 7/10
10 3/4 + 15 1/3
= 10 9/12 + 15 4/12
= 25 13/12
= 26 1/12
7 1/2 + 6 1/3
= 7 3/6 + 6 2/6
= 13 5/6</span>
Answer:
a. 0.9
b. 0.024
c. 0.06
d. 0.2
e. 0.336
Step-by-step explanation:
Since A, B and C are mutually exclusive then P (A U B U C)=P(A)+P(B)+P(C) and P(A∩B∩C)=P(A)*P(B)*P(C).
a.
P (A U B U C)=P(A)+P(B)+P(C)
P (A U B U C)=0.2+0.3+0.4=0.9
b.
P(A∩B∩C)=P(A)*P(B)*P(C)
P(A∩B∩C)=0.2*0.3*0.4=0.024
c.
P(A∩B)=P(A)*P(B)
P(A∩B)=0.2*0.3=0.06
d.
P[(AUB)∩C]=P(AUB)*P(C)
P(AUB)=P(A)+P(B)=0.2+0.3=0.5
P[(AUB)∩C]=0.5*0.4=0.20
e.
P(A')=1-P(A)=1-0.2=0.8
P(B')=1-P(B)=1-0.3=0.7
P(C')=1-P(C)=1-0.4=0.6
P(A'∩B'∩ C')=P(A')*P(B')*P(C')
P(A'∩B'∩ C')=0.8*0.7*0.6=0.336
