Answer:
0.1319 or 13.2%
Step-by-step explanation:
You can solve this using the binomial probability formula.
The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.
Then, we can set the equation as follows:
P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k)
n=4, x=2, k=2
when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157
when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154
when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008
Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)
<h3>Answer: so 3 goes into 12 4 times and 5 times 4 is 20.
Step-by-step explanation:
</h3>
Answer:
12288
Step-by-step explanation:
its a geometric sequence where each term is 4 x the term before it
so the 7th term = 3 *4^6 = 12288
Answer:
P(B and D) = 0.35
Step-by-step explanation:
It is a probability tree diagram. Here to find P(B and D):
apply method:
P(A and B) = P(A) × P(B)
Here given:
So, P(B and D):
