The binomial cumulative probability with p=0.5 for 3+ successes is as follows:
![P(3+)=\sum_{k=3}^6 {{6}\choose{k}}p^k(1-p)^{6-k}](https://tex.z-dn.net/?f=P%283%2B%29%3D%5Csum_%7Bk%3D3%7D%5E6%20%7B%7B6%7D%5Cchoose%7Bk%7D%7Dp%5Ek%281-p%29%5E%7B6-k%7D)
for p=0.5 (50% success rate) it becomes:
![P(3+)=\sum_{k=3}^6 {{6}\choose{k}}0.5^6=\frac{21}{32}=0.65625](https://tex.z-dn.net/?f=P%283%2B%29%3D%5Csum_%7Bk%3D3%7D%5E6%20%7B%7B6%7D%5Cchoose%7Bk%7D%7D0.5%5E6%3D%5Cfrac%7B21%7D%7B32%7D%3D0.65625)
the probability is 0.65625, or about 66%
Answer:
one because it is cilinder
we can have a triangle and we know that there are two angles.
30º and a 45º + 105 =180º angle. applying the sides.
therefore if we have the whole triangle completed we have a constant triangle.
so it tell us we can you’se SOH CAH TOA
we can varrify what kind of triangle we are using.
for example if we were to use Sin I would do
Sin 30/ 2 = sin of 105º/ A = sin=45º/ B
if you would want to solve for sin 30/2 and sin 105, then we solve.
or Sin 30/2 and Sin 105 as well.
with your calculator use sin= 30=.5 and use sin 105º a divide by 1.5 on both sides 1.5= A /sin 105º * 1.5 answer would be 3.86. a is = to 3.86 (Not the answer)
