Fifteen people have been exposed to a particular disease. Each one independently has a 40% chance of contracting the disease. A

valina [46]

Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , $X\sim Binomial(n=15,p=0.40)$

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : $P(X=x)= ^nC_xp^x(1-p)^{n-x}$

Then , the probability that the hospital’s capacity will be exceeded

$P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]$

$=0.095$

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.

Suppose there is a deck where every card has both a single color and a single number. Suppose the colors are Red, Green, and Blu

Elza [17]

Answer:

A. P = 1.7% (rounding to the next tenth)

B. P = 33.3% (rounding to the next tenth)

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of red cards = 20

Number of blue cards = 20

Number of green cards = 20

Total number of cards = 60

2. A. What is the probability that a randomly selected card will be Green 1?

Let's recall that the formula of the probability is:

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 1/60 = 0.017

P = 1.7% (rounding to the next tenth)

B. What is the probability that a randomly selected card will be red?

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 20/60 = 0.333

P = 33.3% (rounding to the next tenth)
