We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is
Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.
We can compute their probability and sum them:
So, the answer is about 36.79%

Answer: 450 rest 100
Step-by-step explanation:
So, we need to calculate this division 100.000/222 and get the rest.
Well, 222 enters in 1000 by 4 times.
222 times 4 is 888
So, 100.000/222 = 4
888-
We subtract 888 from 1000.
That will be 112
100.000/222 = 4
888
112
Now, get the next 0 down next to 112
100.000/222 = 4
888
1120
222 get in 1120 by 5 times.
5 times 222 = 1110
divide 1120 by 1110
100.000/222 = 45
888
1120
1110
That will be 10
100.000/222 = 45
888
1120
==10
Get the next zero down
100.000/222 = 45
888
1120
==100
222 gets in 100 by 0 times.
100.000/222 = 450
888
1120
==100
0
100 subtracted by 0 is 100
100.000/222 = 450
888
1120
==100
0
100
The rest is 100 and the result is 450
Now, you can do the verification:
222 time 450 is 99,900.
If you add the rest to 99,900 it will be 100.000. So the result is good
