This kind of experiments are ruled by Bernoulli's formula. If you have probability p of "success", and you want k successes in n trials, the probability is
It's easier to compute the first probability by difference: instead of computing the probability of the event "at least one of the surveyed eats breakfast", let's compute the probability of its contrary: none of them eats breakfast. So, we want 0 successes in 4 trials, with probability of success 0.34. The formula yields
Since the contrary has probability 17%, our event "at least one of the surveyed eats breakfast" has probability 83%.
As for the second question, the event "at least three of the surveyed eats breakfast" is the union of the events "exactly three of the surveyed eats breakfast" and "exactly four of the surveyed eats breakfast". So, we just need to sum their probabilities:
A rational number is one that u can turn into a fraction.
Anytime u have a whole number and u want to turn it into a rational number, put it over 1.
7 to a rational number would be 7/1
Answer:
The greatest number of arrangements possible would be 5
Step-by-step explanation:
If we look at the x values (in this case # of tulips remaining) we can find the number 20. And we see that there is a line going through it. We then stop at the point and go down to see what number it would fall on on the y axis.
Answer:
Step-by-step explanation:
The step you need next is RQ = RQ.
When I learned this stuff, saying that RQ = RQ is the reflexive property.
Now you have
RP = RS Given
<PRQ = <SRQ The result of a bisected angle.
RQ = RQ A line is always equal to itself.
So the triangles are congruent. The rest follows as stated.
There are infinitely many rational no.s between two no.s
one rational number between 1 and 2 is
11/10
