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.
It is given Nadia goal is to sell 100 tickets out of which she has already sold 17 tickets .
Total number of tickets = 100
Number of tickets sold =17
Number of tickets left = 100-17=83
Nadia can sell 10 tickets in a day
Number of days required to sell remaining 83 tickets if 10 tickets is sold everyday = 83÷10=8.3
Nadia will need minimum of 8+1=9 days to sell the tickets.
