Answer: Part a)
part b)
Step-by-step explanation:
The probability is calculated as follows:
We have proability of any event E =
For part a)
Probability that a red ball is drawn in first attempt =
Probability that a red ball is drawn in second attempt=
Probability that a red ball is drawn in third attempt =
Generalising this result
Probability that a red ball is drawn in [tex}i^{th}[/tex] attempt =
Thus the probability that events occur in succession is
Thus =
Thus our probability becomes
Part b)
The event " r red balls are drawn before 2 whites are drawn" can happen in 2 ways
1) 'r' red balls are drawn before 2 white balls are drawn with probability same as calculated for part a.
2) exactly 1 white ball is drawn in between 'r' draws then a red ball again at draw
We have to calculate probability of part 2 as we have already calculated probability of part 1.
For part 2 we have to figure out how many ways are there to draw a white ball among (r) red balls which is obtained by permutations of 1 white ball among (r) red balls which equals
Thus the probability becomes
Thus required probability of case b becomes
=
Answer:
The answer would be 20.97273616 or (rounded to the nearest cent) would be $20.97
Step-by-step explanation:
The reason for this is that the formula for compounded interest is where A is the total amount, P is the initial amount, r is the growth factor or the percent, n is the number of compounding periods, and t is the time. You would substitute P for 16, r for 0.14 (14%), n for 2 as it compounded semiannually so it for every 6 months instead of 1 year (annual) so is compounded 2 times per year, and t for 2. And just solve the equation and you get that A is equal to 20.97273616 but since we are talking about money( only round if asked) then it would be 20.97.
Hope this helps!!!!
