Start by doing the binomial expansion of (x+y)^6 where x represents success. This is
(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)
We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is
20/64 = .3125 which is 31.25%
There is no solution because x is incorrect.
x should be 32
Answer:
4.4
Step-by-step explanation:
4 (4.4) ≥ 18 does not make sense. 4 x 4.4 = 17.6, which is not more than or equal to 18.
Hey there!
<h3>Guide: </h3>
- Negative & negative = positive
- Positive & negative = negative
- Positive & positive = positive
- Negative & positive = negative
<h3>So, far <u>in your particular question we’re doing</u> <u>positive</u> (7) <u>&</u> <u>negative</u> (-2) so <u>that means your</u> <u>result will most likely be a negative </u></h3><h3 />
<em>Now let’s answer your question, shall we </em>
<h2>7 • (-2) =
<em><u> -14</u></em> </h2>
Good luck on your assignment and enjoy your day!
