Answer:

55-276x

Step-by-step explanation:

To solve this question, you will have to follow some specific principles to prevent error

So to solve this we will have to follow the BODMAS rule

9-3(45x+47x)-2+66

Deal with the bracket first

3(45x+47x)

3(92x)

276x

Then back to the question

9-276x-2+66

Collect like terms

9-2+66-276x

Add comes before substration according to bodmas

9+64-276x

55-276x

This cannot be solved further because they are different from each other

Therefore the final answer is 55-276x

The probability that a mature hen will lay an egg on a given day is 0.80. Hannah has 12 hens. What is the probability that 10 of

OleMash [197]

Answer: 0.28

Step-by-step explanation:

Binomial probability formula :

$P(X=x)=\ ^nC_xp^x(1-p)^x$ , where x = Number of success , n= sample size , p= probability of success for each trial.

Let x = Number of hens lay eggs.

then, p= 0.80

n= 12

For x=10

$P(x=10)=\ ^{12}C_{10}(0.80)^{10}(0.20)^{2}\\\\=\dfrac{12!}{10!2!}\times 0.1073741824\times 0.04\\\\\approx0.28$

Hence, the required probability = 0.28
