Question

What is the probability that one is not nervous around strangers?
The probability that both will be nervous is 0.0324

Answer 1

One is not nervous = 1 - P(None are nervous) - P(Both are nervous)

Answer 2

I feel like it's missing something.. is there any other info?

Answer 3

About 18​% of the population of a large country is nervous around strangers. If two people are randomly​ selected, what is the probability both are nervous around strangers​? What is the probability at least one is nervous around strangers​?

Answer 4

I got the first part I just need help on the second part. I have no idea where to start and where to end.

Answer 5

oh so there you go, 18% is nervous, so the remaining 82% aren't. P(none are nervous)=0.82
1-.82-.0324

Answer 6

Meaning
1 - P(none are nervous) - P(both are nervous)

Have someone double check tho, I'm not too sure about probability

Answer 7

So I would find the remaining and subtract it from 1?

Answer 8

you need to find P that none are nervous, which is 1-.18=.82
P(one out of two is not nervous) = P(only one out of the two is nervous) = 1 - P(none are nervous) - P(both are nervous)

Answer 9

= 1 - 0.82 - 0.0324

Answer 10

0.1476 isn't right.

Answer 11

I don't understand how 0.3276 is the answer.

Answer 12

wait it said at least one,one gives probability of exactly one

Answer 13

I don't understand what you're trying to say.

Answer 14

so P at least one is P exactly one + P exactly two
