Answer:

S = {PQ, QP, PR, RP, QR, RQ}

P = Pat Q = Quinlan R = Rashad

Now, the teacher is going to draw out of the hat one first, without replacement, and then draw another one. The first one will be the president, and that could be P, Q or R, and the second one is the Vice president, and since one has already being drawn, that could only be two fellows. The total of likely outcomes is PQ,QP, PR, RP, QR, RQ, one paired up with either of the two remaining in the hat.

I don't understand proportional relationship can u help?

Reptile [31]

Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D

Consider the probability that fewer than 26 out of 107 cell phone calls will be disconnected. Assume the probability that a give

anyanavicka [17]

Answer:

We assume the condition of independence satisifed.

We need to check the following conditions in order to use the normal approximation.

$np=107*0.98=104.86 \geq 10$

$n(1-p)=107*(1-0.98)=2.14 < 10$

So we see that we satisfy the first condition, but the second no so then we can't apply the approximation for this case, since we need both conditions at the same time in order to use the normal approximation.

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=107, p=0.98)$
