Police estimate that 25% of drivers drive without their seat belts. If they stop 6 drivers at random, find the probability tha

Furkat [3]

Answer:

17.80% probability that all of them are wearing their seat belts.

Step-by-step explanation:

For each driver stopped, there are only two possible outcomes. Either they are wearing their seatbelts, or they are not. The drivers are chosen at random, which mean that the probability of a driver wearing their seatbelts is independent from other drivers. So we use the normal probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Police estimate that 25% of drivers drive without their seat belts.

This means that 75% wear their seatbelts, so $p = 0.75$

If they stop 6 drivers at random, find the probability that all of them are wearing their seat belts.

This is $P(X = 6)$ .

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 6) = C_{6,6}.(0.75)^{6}.(0.25)^{0} = 0.1780$

17.80% probability that all of them are wearing their seat belts.

Sam needs to cut a piece of sheet metal into 8 pieces. It takes him 5minutes to make each cut. How many cuts will sam make?

Virty [35]

This is actually a trick question if you were to take this question head on. Say for instance you are cutting all the pieces from the same sheet of metal, the equation would NOT be 8 times 5 equals 40 minutes, but rather 7 times 5 equals 35 minutes. this is because on the 7th cut, it takes that from 6 sheets of metal to 8 because you get 2 from that cut. Take for instence, a Hersheys candy bar. It is 3 bars thick, but it only takes 2 breaks to sever the 3 strips. So, that being said, sam will make 7 cuts and those 7 cuts will make a times of 35 minutes.

Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.
