What is the probability of getting two heads in an experiment of tossing two coins at the same time? h 1/4 С a 50% 0 I don't kno
1 answer:
The probability of tossing a coin of getting head is 1/2 because there are two faces in the coin one of them is head
P(h) = 1/2
Since there are two coins will tossing together, then the probability of each coin getting a head is 1/2
We need to getting head in both, then we will multiply the two of them
Then the probability is 1/4

Answer:
The confidence level is 95% or 0.95.
Step-by-step explanation:
Consider the provided information.
Results of a poll stated that 40% of U.S.
If you want to test the claim at alpha = 0.05.
As we know:
Confidence level = 1 - significance level ()
Confidence level =
Confidence level =
Therefore, the confidence level is 95% or 0.95.
Answer:
a) 0.122
b) 3.35 × 10⁻⁴
c) 0.1071
Step-by-step explanation:
Here we have the Poisson process given by
Where:
λ = Rate = 4 bites/hour and
t = Length of time that is
Mean = λt
Where k = 6 fishes bites and t = 2 hours we have
b) The probability that he fails to catch any fishes during the first two hours is the probability t that he catches 0 fish as follows
(c) Here we have
For 1 fish caught in two times we have first time no fish and second time he caches a fish gives
0.122×(1-0.122) = 0.1071
Hello,
Let's assume k the ratio.
