Answer with Step-by-step explanation:

For a given Binomial event with  probability of success 'p' the probabolity of 'r' success in 'n' trails is given by

P(E)=\frac{n!}{(n-r)!\cdot r!}p^r\cdot (1-p)^{n-r}

Thus for given 4 trails (n = 4) we have

Part 1)

Probability of 1 success is  

P(E_1)=\frac{4!}{(4-1)!\cdot 1!}\cdot 0.7^1\cdot (1-0.7)^{4-1}\\\\\therefore P(E_1)=0.076

Part 2)

Probability of 2 successes

P(E_2)=\frac{4!}{(4-2)!\cdot 2!}\cdot 0.7^2\cdot (1-0.7)^{4-2}\\\\\therefore P(E_2)=0.265

Part 3)

Probability of at least 1 success

P(E)=1-(1-p)^n\\\\\therefore P(E_3)=1-(1-0.7)^{4}=0.992

What is the area of a circle with a diameter of 12.6 in.?
Zepler [3.9K]

Hey there! I'm happy to help!

To find the area of a circle, you square the radius and then multiply by pi (3.14 in our case).

The radius is half of the diameter.

12.6/2=6.3

We square this.

6.3²=39.69

We multiply by 3.14

39.69×3.14=124.6266

We round to the nearest hundredth, giving us an area of 124.63 in².

Now you can find the area of a circle! Have a wonderful day! :D
