Answer:
P (T) = 1/4
P ( T | F ) = 1/2 = P(F)
The events are not independent.
Step-by-step explanation:
Let F the event of picking the white ball first
P (F)= 1/2 ( picking the white ball first)
Let T be the event of getting the white ball twice,
P (T) = P( getting white ball) * P( getting white ball)
=( 1/2)*(1/2)
= 1/4
Here P(T∩F) = P(T) because the probability of getting the white balls is the same as probability of getting the white ball first both the times.
P ( T | F ) = P (T∩F)/ P(F)
= (1/4)/ (1/2)
= (1/2)
= 1/2 = P(F)
For the events to be independent the conditional probability P ( T | F ) must be equal to P(T).
Hence the events are not independent.
Question 1= would equal 63 but why is there no 63?(did you type the answers right? or the angles right?
47+70=117
180-117=63
question 2 would be 36
54+90=144
180-144=36
Answer:
1, 2, 4, 5, 8, 10, 20, 40

Answer:
Step-by-step explanation:
First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.
60 / 4 = 15
Now we divide their total of $210 by their hourly rate of $15 to find how many hours it would take.
210 / 15 = 14
I would take 14 hours to earn $210.
<u>If im right brainliest plz </u>
Hope this helps :)
