A code consist of a two digit number chosen from 00 to 49 followed by a letter of the alphabet. What is the probability the code
1 answer:
Answer:
<em>The probability that code is will be
</em>
Step-by-step explanation:
From 00 to 49, there are total 50 two-digit numbers.
The total number of alphabets is 26.
So, the probability of choosing 14 from all 50 two digit numbers will be:
and the probability of choosing '' from all 26 alphabets will be:
Thus, the probability that code is is

Answer:
a) The mean number of cases is 0.14608 cases.
b) The probability that the number of cases is exactly 0 or 1 is 0.990.
c) The probability of more than one case is 0.010
d) No, because the probability of more than one case is very small
Step-by-step explanation:
We can model this problem with a Poisson distribution, with parameter:
a) The mean amount of cases is equal to the parameter λ=0.14608.
b) The probability of having 0 or 1 cases is:
c) The probability of more than one case is:
d) The cluster of 4 cases can not be due to pure chance, as it is a very high proportion of cases according to the average rate. Just having more than one case has a probability of 1%.
