Answer:the probability that a pensioner catches a flu is 0.3 or
Step-by-step explanation:
<u>Data:</u>
a) Pensioners who have had a flu jab =
b) Pensioners who did not had a flu jab = 1 - =
For the first pair of arrows: a is the probability of the upper arrow and b is the probability of the lower arrow.
<em>If pensioner have had a flu jab, the probability of catching flu is </em>
Data:
c) Catching flu =
d) Not catching flu = 1 - =
The second pair of arrows on the top: Top arrow is c and bottom arrow is d
<em>If pensioner did not have a flu jab, the probability of catching flu is </em>
<u>Data:</u>
e) Catching flu =
f) Not catching flu = 1 - =
The second pair of arrows on the bottom: Top arrow is e and bottom arrow is f.
Q) Probability pensioner catches a flu
P(catches the flu given that he had the flu jab) + P(catches the flu given that he did not have the flu jab)
( x
) + (
x
)
= 0.02 + 0.28
= 0.3
Therefore, the probability that a pensioner catches a flu is 0.3 or
