About 1919% of the population of a large country is nervous around strangersnervous around strangers. if two people are randoml y selected, what is the probability both are nervous around strangersnervous around strangers? what is the probability at least one is nervous around strangersnervous around strangers?
1 answer:
<span>Probability that a person is math phobic = 19% = 19/100
a) the probability that both are nervous around strangers</span>
<span>P (A)
= 19/100 * 19/100
= 361/10000
= 0.0361</span>
<span>
b) The probability that both are not nervous around strangers</span>
<span>P (B) = 81/100 * 81/100
= 0.6561</span>
<span>
The probability that at least one person is nervous around strangers i.e. P'(B)
= 1 - P(B)
= 1 - 0.651
= 0.3439</span>

A vertex is the common point that two lines or rays diverge from.
Solution :
Given initial population = 300
Final population after 1 day = 800
Number of days = 6
∴
P(0) = 300 P(1) = 300
We need to find P(8).
When P(0) = 300
∴ c = 300
∴
When P(1) = 800
∴ k = 750
So, P(8) is
= 11,614
So the population becomes 11,614 after 8 days.
