Step-by-step explanation:
Answer:
As the first event outcome affects the probability of the outcomes of the second event, both events are dependant.
Step-by-step explanation:
The events are not independent.
The reason is that the first event affects the outcome of the second event.
This happen because the if we choose a comic book for ourselves, there is a probability of 6-1=5 out of 5+5=10 of getting a comic book for our friend (P=50%).
If we choose a nonfiction book four ourselves, the probability of getting a comic book for our friend is 6 in 10 (P=60%).
As the first event outcome affects the probability of the outcomes of the second event, both events are dependant.
O= 4 & -4
Explain: it shows on the paper
A1=8
common ratio=r
sum of 6 terms
S=a1+a2+a3+...+a6
=a1(1+r+r^2+...+r^5)
=a1(r^6-1)/(r-1)
but we're given S=74648
=>
8(r^6-1)/(r-1)=74648
Cross multiply and solve for r (by trial and error)
r^6-1=9331(r-1)
r=6
so
a(3)=a1*r^(3-1)
=8*(6^2)
=288
