(20+4)x4 multiply 4x20=80 and 4x4=16. Add 80+16 and get 96.
Answer:
50 g butter
45 g caster sugar
5 g chocolate chips
Step-by-step explanation:
First do 300 over 400 and you will get 1/4. That means he used 1/4 less of his ingredients. So you multiply everything by 1/4 and you will get 50 g of butter, 45 g of caster sugar, and 5 g of chocolate chips. If my explanation is not clear enough, there is work to show you the step.
Step-by-step explanation:
<h2>You can solve this using the binomial probability formula.</h2><h2>The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.</h2><h2>Then, we can set the equation as follows:</h2><h2> </h2><h2>P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k) </h2><h2>n=4, x=2, k=2</h2><h2>when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157</h2><h2>when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154</h2><h2>when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008</h2><h2>Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)</h2>
The ones that end in self are object
