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

Answer:
14 ounces of blue paint
Step-by-step explanation:
The ratio of blue to yellow is 2:7
To solve this problem we can make a proportion:
2/7=x/49
the numerator represents the blue paint, the denominator represents the yellow paint
To solve the proportion you have to cross multiply:
2*49=7*x
x=14
She needs to add 14 oz of blue paint
