1. The probability would be 5/100, simplified would be 1/20.

2. The probability would be 1600/10,000, simplified would be 16/100.

3. A vowel would be 6/13 and a constant would be 7/13.

4. The experimental probability of getting heads would be 12/20, simplified 3/5. This may differ from the theoretical probability because you are only flipping it 20 times.

I hope this helped! Brainliest? :) -Raven❤️

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round t
matrenka [14]

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257
