Roll a die and consider the following two events={2, 3, 6}, event ={1, 5, 6}. Are the events E and F independent?Choose the correct answer below.- No, because the probability of F occurring is higher if it is known that E has occurred.- No, because there is at least one roll which leads to both E and F occurring.- Yes, because the probability of F occurring is higher if it is known that E has occurred.- Yes, because each roll of the die is an independent event.

We learned in Exercise 4.18 that about 90% of American adults had chickenpox before adulthood. We now consider a random sample of 120 American adults. (a) How many people in this sample would you expect to have had chickenpox in their childhood? And with what standard deviation? (b) Would you be surprised if there were 105 people who have had chickenpox in their childhood? (c) What is the probability that 105 or fewer people in this sample have had chickenpox in their childhood? How does this probability relate to your answer to part (b)?

Suppose you want to find the difference of two sinusoidal currents, given as follows: i1(t)=I1 cos(ωt+ϕ1) and i2(t)=I2 cos(ωt+ϕ2). If you stay in the time domain, you will have to use trigonometric identities to perform the subtraction. But if you transform to the frequency domain, you can simply subtract the phasors I1 and I2 as complex numbers using your calculator. Make sure that all of your time-domain currents are represented using the cosine function before you apply the phasor transform. Your answer will be a phasor, so you will need to inverse phasor-transform it to get the answer in the time domain. This is an example of a problem that is easier to solve in the frequency domain than in the time domain. Use phasor techniques to find an expression for i(t) expressed as a single cosine function, where i(t)=[250cos(377t+30∘)−150sin(377t+140∘)] mA. Enter your expression using the cosine function. Round real numbers using two digits after the decimal point.
