Seventeen people have been exposed to a particular disease. Each one independently has a 40%chance of contracting the disease. A hospital has the capacity to handle 10 cases of the disease. What is the probability that the hospital's capacity will be exceeded?

a. 0.011

b.0.035

c. 0.092

d. 0.965

e. 0.989

Short Answer

Expert verified

(b) The probability that the hospital's capacity will be exceeded is 0.035.

Step by step solution

01

Given Information

Given,

The number of people who have been exposed to disease. (n)=17

The likelihood of developing the disease(p)=40%=0.40

Used formula:

The probability formula for a binomial distribution is:

P(X=x)=nxpx(1-p)n-x

02

Explanation for correct option

The likelihood that hospital capacity will be surpassed can be calculated as follows:

P(X>10)=111717x(0.40)x(1-0.40)17-x=P(X=11)+P(X=12)+.+P(X=17)=1711(0.40)11(1-0.40)17-11+1712(0.40)12(1-0.40)17-12++1712(0.40)17(1-0.40)17-17=0.035

Therefore, the correct option is (b) that is0.035.

03

Explanation for incorrect option

(a) The probability that the hospital's capacity will not be0.011.

(c) The probability that the hospital's capacity will not be 0.092.

(d) The probability that the hospital's capacity will not be 0.965.

(e) The probability that the hospital's capacity will not be0.989.

Large Counts condition To use a Normal distribution to approximate binomial probabilities, why do we require that both npand n(1-p) be a t least 10?

Skee BallAna is a dedicated Skee Ball player (see photo in Exercise 4) who always rolls for the 50-point slot. The probability distribution of Ana’s score Xon a randomly selected roll of the ball is shown here. From Exercise 8, μX=23.8.

(a) Find the median of X.

(b) Compare the mean and median. Explain why this relationship makes sense based on the probability distribution.

Geometric or not? Determine whether each of the following scenarios describes a geometric setting. If so, define an appropriate geometric random variable.

a. A popular brand of cereal puts a card bearing the image of 1 of 5 famous NASCAR drivers in each box. There is a 1/5chance that any particular driver's card ends up in any box of cereal. Buy boxes of the cereal until you have all 5 drivers' cards.

b. In a game of 4-Spot Keno, Lola picks 4 numbers from 1 to 80 . The casino randomly selects 20 winning numbers from 1 to 80 . Lola wins money if she picks 2 or more of the winning numbers. The probability that this happens is \(0.259\). Lola decides to keep playing games of 4-Spot Keno until she wins some money.

Get on the boat! A small ferry runs every half hour from one side of a large river to the other. The probability distribution for the random variable Y = money collected (in dollars) on a randomly selected ferry trip is shown here.

Part (a). FindP(Y<20)P(Y<20) . Interpret this result.

Part (b). Express the event “at least $20 is collected” in terms of Y. What is the probability of this event?

a. Assume that B and Ware independent random variables. Explain what this means in context.

b. Calculate and interpret the standard deviation of the difference D(Bus - Walk) in the time it would take Sulé to get to work on a randomly selected day.

c. From the information given, can you find the probability that it will take Sulé longer to get to work on the bus than if he walks on a randomly selected day? Explain why or why not.
