Answer:
(B) Jenner's research led to the creation of a small pox vaccine
Using conditional probability, it is found that if a flight is on time, there is a 0.5926 = 59.26% probability it was from company Amira.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the percentages associated with a on-time flight are given as follows:
- 80% of 50%(Company Amira).
Hence:
P(A) = 0.8 x 0.5 + 0.65 x 0.3 + 0.4 x 0.2 = 0.675.
The probability of both being on time and from Amira is given by:
Hence the conditional probability is given by:
If a flight is on time, there is a 0.5926 = 59.26% probability it was from company Amira.
