Answer:

3/10 of the total distance to her grandmother's house was traveled on Sunday

Step-by-step explanation:

Carly's family traveled distance of Saturday = \frac{3}{10}

Remaining distance =1-\frac{3}{10}=\frac{7}{10}

They traveled 3/7 of the remaining distance on Sunday.

So, Distance traveled on Sunday =\frac{3}{7}(\frac{7}{10})

Distance traveled on Sunday =\frac{3}{10}

Fraction of the total distance to her grandmother's house was traveled on Sunday =\frac{3}{10}

Hence 3/10 of the total distance to her grandmother's house was traveled on Sunday

The likelihood that a patient with a heart attack dies of the attack is 0.04 (i.e., 4 of 100 die of the attack). Suppose we have
Sonbull [250]

The probability solved by binomial distribution that all will survive is 0.8154.

<h3>What is Binomial distribution? </h3>

When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.

Computation of probability of all survived people from heart attack;

A heart attack patient has a 0.04 percent chance of dying from the attack (i.e., 4 of 100 die of the attack).

What is the likelihood that each of the five patients who experience a heart attack will survive?

We'll refer to a victory in this scenario as a heart attack (p = 0.04). In other words, we are interested in the likelihood that none of our n=5 patients will die (0 successes).

Each attack has a chance of being fatal or not, with a probability of 4 percent for all patients, and each patient's result is independent.

Assume for the purposes of this example that the five individuals being examined are unrelated, of the same age, and free of any concomitant disorders.

By binomial distribution,

\begin{gathered}P(0 \text { successes })=\frac{5 !}{0 !(5-0) !} 0.04^{0}(1-0.04)^{5-0} \\P(0 \text { successes })=\frac{5 !}{5 !}(1)(0.96)^{5}=(1)(1)(0.8154)=0.8154\end{gathered}

Therefore, with a 4 % chance that anyone will die, there is an 81.54% chance that every patient will survive the onslaught. The outcomes in this example could be 0, 1, 2, 3, 4 or 5 successes (fatalities).

In survey 17/25 of the people surveyed have a cat. what percent of the people surveyed have a cat?
mestny [16]

Answer:

The percentage of the people surveyed that have a cat is 68%

Step-by-step explanation:

we know that

To find the percentage of the people surveyed that have a cat, multiply the given fraction by 100

so

\frac{17}{25}*100=17*4=68\%

You are at a campus party where there are a total number of n people. The host asked everyone to put their phones in a bowl whil
kirill [66]

Answer:

1, \frac{m}{n}, \frac{1-m}{n}.

Step-by-step explanation:

probability = \frac{Number of Possible Outcomes}{Total Outcomes}

Total number of persons in the party = n

a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person

   = \frac{1}{n} × n = 1.

     No of first m persons to pick = m

     No of last m persons to pick = 1 - m

b) Pr (first m persons to pick each gets their phones back) = \frac{m}{n}

c) Pr( first m persons get a phone belonging to last m persons) = \frac{1-m}{n}
