Find each probability if a coin is tossed 5 times.
$P(\text { at least } 4 \text { tails) }$

All right, We're tossing four coins and we want to find the probability of tossing not all tales. So if we think about this for a minute, all tales This event we represented in our samples face as four teas and row, so t t t t is the event that we toss all tales. But we're interested in the event that we toss Not all tales. So we could think about that as the probability of the compliment of this event that we described above and remembering our complement rule that is the same thing as one minus the probability of getting all tales. So if we look in our sample space, the probability of getting four tails is going to be one out of 16. Because there's only one way that can occur out of the 16 possible outcomes listed in our sample space. So this is one minus one out of 16 which is 15 out of 16. For that probability,

We're tossing four coins and we want to find the probability of not tossing all tales probability of not more tales. So this is just equal to one minus the probability of four tales, cause it's the compliment of that. Okay, so that's one minus and probability of causing four tails is going to be one out of 16 so our answer is going to be 15 out of 16.

And this problem were asked to find the probability of tossing all tales in an experiment where we're tossing for coins. This event on Leah has one element, which is getting tails four times in a room. Since all the outcomes and the samples face are equally likely, we can find the probability of this event by dividing the number of elements in the event by the number of elements in the sample space. The number of elements in the event is just one, and a number of elements of the sample space is 16 so the probability of tossing all tales is one every 16.

Okay, so as to find the probability of tossing Alltel's. So that's this foretells. And if you look at a subspace was only one that includes four tails. So that's one over entire Cypress Trace, which is 16.
