select all statements below that are true about the binomial distribution shown on the right.\nthe bar for any number k represents the probability of getting k successes in 5 flips.\nthe number of successes, k, can range from 0 (no success) to 5 (all successes).\neach coin - flip is independent. it is not affected by any other coin - flip.\nfor 5 coin flips, p(2 heads)=p(3 heads).\nthe sum of the probabilities shown in the binomial distribution is 1.
Answer
Explanation:
Step1: Analyze binomial distribution concept
In a binomial distribution of coin - flips, the bar for (k) represents the probability of (k) successes in (n) flips. Here (n = 5), so the bar for any number (k) represents the probability of getting (k) successes in 5 flips. This statement is true.
Step2: Determine range of successes
The number of successes (k) in (n) independent Bernoulli trials (coin - flips) can range from (0) (no successes) to (n) (all successes). Since (n = 5), (k) can range from (0) to (5). This statement is true.
Step3: Check independence of coin - flips
Coin - flips are independent events. The outcome of one coin - flip does not affect the outcome of any other coin - flip. This statement is true.
Step4: Compare probabilities
The probability mass function of a binomial distribution is (P(X=k)=C(n,k)p^{k}(1 - p)^{n - k}), where (n = 5) and (p=\frac{1}{2}) for a fair coin. (P(2\text{ heads})=C(5,2)(\frac{1}{2})^{2}(1-\frac{1}{2})^{3}=\frac{5!}{2!(5 - 2)!}\times(\frac{1}{2})^{5}=10\times\frac{1}{32}), and (P(3\text{ heads})=C(5,3)(\frac{1}{2})^{3}(1 - \frac{1}{2})^{2}=\frac{5!}{3!(5 - 3)!}\times(\frac{1}{2})^{5}=10\times\frac{1}{32}). So (P(2\text{ heads})=P(3\text{ heads})), this statement is true.
Step5: Sum of probabilities
The sum of the probabilities in a probability distribution (including a binomial distribution) is (1), not (p). This statement is false.
Answer:
The bar for any number (k) represents the probability of getting (k) successes in 5 flips; The number of successes, (k), can range from 0 (no success) to 5 (all successes); Each coin - flip is independent. It is not affected by any other coin - flip; For 5 coin - flips, (P(2\text{ heads}) = P(3\text{ heads}))
