X + 3 • ( 10 + y ) - 7x - 4
x + 30 + 3y - 7x - y
x - 7x + 3y - y + 30
-6x + 2y + 30
Answer:
31.3%
Step-by-step explanation:
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 successes. Since the probability of success 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% Rounding yo the nearest tenth gives us
Do you mean millions? If so, please write 4,110,000, which is in terms of millions and is in standard form. Otherwise, ensure that you have copied down this problem correctly.
