What exactly are u asking? If u need it in # for it is 7-3÷v
I don't know what posts are but i'm assuming you would subtract 21 from 17 and get 4.
Answer:
a. 0.76
b. 0.23
c. 0.5
d. p(B/A) is the probability that given that a student has a visa card, they also have a master card
p(A/B) is the probability that given a student has a master card, they also have a visa card
e. 0.35
f. 0.31
Step-by-step explanation:
a. p(AUBUC)= P(A)+P(B)+P(C)-P(AnB)-P(AnC)-P(BnC)+P(AnBnC)
=0.6+0.4+0.2-0.3-0.11-0.1+0.07= 0.76
b. P(AnBnC')= P(AnB)-P(AnBnC)
=0.3-0.07= 0.23
c. P(B/A)= P(AnB)/P(A)
=0.3/O.6= 0.5
e. P((AnB)/C))= P((AnB)nC)/P(C)
=P(AnBnC)/P(C)
=0.07/0.2= 0.35
f. P((AUB)/C)= P((AUB)nC)/P(C)
=(P(AnC) U P(BnC))/P(C)
=(0.11+0.1)/0.2
=0.21/0.2 = 0.31
Answer:
<h2>36</h2>
Step-by-step explanation:
The median is the value that separates the higher half from the bottom half of the data sample (middle value).
We have
34, 36, 30, 37, 40, 30, 42
Write from the smallest to the largest number
30, 30, 34, 36, 37, 40, 42
Step-by-step explanation:
Use the equation ?/45.20 = 35\100 and what you get is your answer
Hope this helps
