Answer:

Step-by-step explanation:

pythagorean theorem. a^2+b^2=c^2

1.5^2+b^2=6^2

2.25+b^2=12

12-2.25=b^2

b^2=9.75

take the square root

b=3.12

Answer: b = 5.809

Explanation:

Use Pythagorean’s Theorem

a^2 + b^2 = c^2 => b^2 = c^2 - a^2

b^2 = 6^2 - 1.5^2
b^2 = 36 - 2.25
b^2 = 33.75
b = sqrt(33.75)
b = 5.809

A human gene carries a certain disease from the mother to the child with a probability rate of 42%.That is, there is a 42% chanc

soldi70 [24.7K]

Answer:

Option B.

Step-by-step explanation:

It is given that there is a 42% chance that the child becomes infected with the disease.

Let A be the event that the child becomes infected with the disease.

$P(A)=42%=0.42$

A' be the event that the child is not infected.

$P(A')=1-P(A)=1-0.42=0.58$

Assume that the infections of the three children are independent of one another.

Let X be the number of children get the disease from their mother.

The probability that all three children are free from disease is

$P(X=0)=P(A')\cdot P(A')\cdot P(A')=0.58\cdot 0.58\cdot 0.58=0.195112$

We need to find the probability that at least one of the children get the disease from their mother.

$P(X\ge 1)=1-P(X=0)$

$P(X\ge 1)=1-0.195112$

$P(X\ge 1)=0.804888$

$P(X\ge 1)\approx 0.805$

The probability that at least one of the children get the disease from their mother is 0.805.

Therefore, the correct option is B.
