a)
The probability both are math phobic: 0.0144 or 1.44%
b)
The probability that atleast one is math phobic is: 0.2256 or 22.56%
It is given that:
About 12% of the population of a large country is math phobic.
This means that the probability that a randomly selected person is math phobic is: 0.12
If two people are randomly selected.
a)
The probability both are math phobic:
This means that the first person selected is math phobic and the second person selected is also math phobic.
= 0.12×0.12
= 0.0144
which in percent is: 1.44%
b)
The probability that atleast one is math phobic is:
1-none is math phobic.
= 1-(1-0.12)×(1-0.12)
=1- 0.88×0.88
= 0.2256
which in percent is: 22.56%
