Probabilities are used to determine the chances of events.
The given parameters:
---- the number of candy bars
---- the probability of selling a candy bar
<u>(a) Name distributions</u>
The distribution of X is represented as:
Where:
So, the name distribution of X is
<u>(b) The probability that the last candy is sold at the 11th house</u>
This means that:
--- the number of previous houses
--- the previous number of candies
--- the given probability of selling a candy
The probability is calculated using:
This gives
Approximate
Hence, the probability that the last candy is sold at the 11th house is 0.1003
<u>(b) The probability he sells the candies on or before the 8th house</u>
The probability is calculated using:
This gives
---- approximated
Hence, the probability he sells the candies on or before the 8th house is 0.1737
