A study conducted on American families shows that 18% of these families have medical bills of more than $10,000. Find the probability that among 5 randomly selected American families, at least one has medical bills of more than $10,000.

the probability is 0.6293

Step-by-step explanation:

The computation of the probability is shown below:

Given that

n = 5

P = 0.18

As it represents the  binomial distribution

P(X = x) =  × p^x × (1 - p) ^(n - x)

P(X > 1) = 1 - P(X < 1)

= 1 - P(X = 0)

= 1 - ( × (0.18) ^0 × (0.82) ^5)

= 1 - 0.3707

= 0.6293

hence, the probability is 0.6293

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
