a.)

${4\choose3}*.25^3*(1-.25)=.046875$

b.)

Porbability of at most 3 successes is equal to 1-p(4)

p(4)=

${4\choose4}*.25^4=.003690625$

1-.003690625=.99609375

c.)

two or more failures is equa lto

p(0)+p(1)+p(2)=

${4\choose0}*.25^0*(1-.25)^4+{4\choose1}*.25^1(1-.25)^3+{4\choose2}*.25^2*(1-.25)^2=.94921875$

2x-4/5=4<br> plsss answer quick

nikdorinn [45]

Answer:

Step-by-step explanation:

$\frac{2x - 4}{5} =4$

First of all multiply through by 5 to eliminate the fraction

That's

$5 \times \frac{2x - 4}{5} = 4 \times 5 \\ 2x - 4 = 20$

Next using the addition property add 4 to both sides of the equation

We have

$2x - 4 + 4 = 20 + 4 \\ 2x = 24$

<u>Divide both sides by 2</u>

$\frac{2x}{2} = \frac{24}{2}$

We have the final answer as

Hope this helps you
