Step-by-step explanation:
There is 10 questions which in this case are the trials.
We know we can either get a question right or wrong so the two outcomes are right or wrong.
The probability that a student choose the right outcome is 1/4. since there is one right answer out of 4 chocies.choices.
Yes, the trials likelihood outcome of each outcome is the same. so it's independent
Answer:
3:15 pm
Step-by-step explanation:
You can imagine that they go in a circle (we can do whatever we want in theoretical math and physics). By doing so we know we can obtain a cosinusoidal wave by projecting the motion on a plane. Each one of the buses has a period (minimum time after what they're in the same point again). For the first one it's 15 minutes, for the second one it's 20 minutes. We have to take the least common multiple of the periods, that is 75 minutes. So They'll meet every 75 minutes. Add 75 minutes (1h and 15 minutes) to 2pm and there you go.
Rewrite the expression on the left using the distributive property
The answer is the fraction is 66/100 or simplified, 2/3<span />
