Credit Cards A survey of consumer finance found that 25.4$\%$ of credit-card -holding families hardly ever pay off the balance. Suppose a random sample of 20 credit-card-holding families is taken. Find the probabilities of each of the following results. Source: Statistical Abstract of the United States.
Exactly 6 families hardly ever pay off the balance.

Okay. This question tells us that 25.4% of families don't pay off their credit card balance, and it asks us to find the probability that at least four out of a sample of 20 families do not pay off their balance. So we want the probability of at least four, which means we could have four families, not pay five families, not pay six families, not pay all the way up to all 20. So, in order to avoid finding all of the East probabilities, we can shorten our work by noting this is just all the events that could happen. So one minus the events that we don't want. So we don't want to include the probability of 01 two or three and notice that this is the probability from 0 to 3, so we can write it as the probability that X is less than or equal to three. So this is a cumulative probability, which we confined using our calculator. So this is one minus by no meal CDO for cumulative, with 20 trials a success probability of 0.254 and we want the key milled of probability up to three. And doing this gets us an answer of 0.7868 as our final probability

Okay. This question tells us that 25.4% of families don't pay off the balance on a credit card, and it wants us find the probability that no more than five out of the 20 families in our sample don't pay. So you want the probability of no more than five, and that's equal to well, we could have zero families not pay one family, not pay two families, three for or five. So this is quite a lot of work to just use the binomial theorem to find each of these. So what we're gonna do instead is noticed that this is the probability that we have less than or equal to five families. So we want the probability upto X equals five, including it, which we have the binomial cumulative distribution function command on our calculator to find. And we have 20 trials with a success rate of 200.254 and we want the probabilities up till five successes. And if we plug this one in So our calculator here we get point 60 09 as our final probability

Look at this question now. This question says, this is our debut. This question says, Find the probability that a randomly selected worker has one month income or more set aside for emergencies, given that the workers female given that the workers female now the workers female, which means we know that our sample size is 1 45. And what is the probability? Select the probability that a randomly selected worker has one month's income or more set aside for emergencies. This means this is going to be my favorable outcomes. So this will be 62 divided by 1 45. This is my first answer. Let's look at the second one. The second one says, find the probability that a random dis elected workers female. Okay, given that the worker has less than one month and come set aside for emergencies less than one month income. So this time this is my sample size and I'm gonna find the probability that a worker is female. So my probabilities 83 by 1. 49 83 divided by 1 49. These are going to be my answers
