UkoKoshka [18]

Answer:

The probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

Given : A scientist inoculates​ mice, one at a​ time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.

To find : What is the probability that 8 mice are​ required? The probability that that 8 mice are required is nothing ?

Solution :

Applying binomial distribution,

P(X=r)=^nC_r p^rq^{n-r}

Where, p is the probability of success p=\frac{2}{7}

q is the probability of failure q=1-p, q=1-\frac{2}{7}=\frac{5}{7}

n is total number of trials n=8

r=3

Substitute the values,

P(X=3)=^8C_3 (\frac{2}{7})^3 (\frac{5}{7})^{8-3}

P(X=3)=\frac{8!}{3!5!}\times \frac{8}{343}\times (\frac{5}{7})^{5}

P(X=3)=\frac{8\times 7\times 6}{3\times 2\times 1}\times \frac{8}{343}\times \frac{3125}{16807}

P(X=3)=0.2428

Therefore, the probability that 8 mice are​ required is 0.2428.

Step-by-step explanation:

<u><em>║Given info║:</em></u>

<em>Factor completely: </em>4x^2 +8x -5

<u><em>Solution~:</em></u>

<em>Breaking the expression~:  </em>\left(4x^2-2x\right)+\left(10x-5\right)

<em>Factor out 2x from 4x² -2x : 2x(2x-1)</em>

<em>Factor out 5 from 10x - 5 : 5(2x - 1)</em>

<em>Put together: </em>=2x\left(2x-1\right)+5\left(2x-1\right)

Factor out 2x - 1: =\left(2x-1\right)\left(2x+5\right)
