The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%
<h3>
How to find the probability?</h3>
We know that roughly 75% of the students take the bus, then, if we select a student at random.
- There is a probability of 0.75 that the student takes the bus.
- There is a probability of 0.25 that the student does not take the bus.
The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:
p = (0.75)^9 = 0.075
Then we have:
P = 1 - 0.075 = 0.925
The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

divide 3000 by 10 to get a tenth of 3000
Answer:
x = 20
Step-by-step explanation:
Lines l and m are parallel so the sum of given angles is = 180
3x + 12 + 5x + 8 = 180 add like terms
8x + 20 = 180 subtract 20 from both sides
8x = 160 divide both sides by 8
x = 20 replace x with 20 in given expression to calculate any measure.
