On a random cross medical checkup in Muscat airport, the statistic shows 45% of the travelers are form region A, 35% are form region B, and 20% are form region C. The Medicine doctors have found that 6% of the travelers form region A, 7% of the travelers form region B, and 5% of the travelers form region C are infected by COVID-19. One week later, an infected traveler went for recheck-up. Find the probability he/she region B
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

Given,
On a random cross medical checkup in Muscat airport, the statistic shows 45% of the travelers are form region A, 35% are form region B, and 20% are form region C. The Medicine doctors have found that 6% of the travelers form region A, 7% of the travelers form region B, and 5% of the travelers form region C are infected by COVID-19.
That is,
Let I be the infected traveler by COVID-19
P(A)=0.45
P(B)=0.35
P(C)=0.2
P(A|I)=0.06
P(B|I)=0.07
P(C|I)=0.05
