Question

78. For a binomial distribution with n=10, P=0.5, the probability of zero or more success
is,​

Answer 1

Answer:

zero is the right answer

Step-by-step explanation:

We also say that X has a binomial distribution with parameters n and p. The following ... X is a binomial random variable with parameters n = 5, p = 0.5. ... Find the probability that X is zero.

Answer 2

The probability of getting a 0 or success is 1 only.

Given:
$n=10$

$p=0.5$

To find:

The probability of zero or more success.

Solution:
We have been given the number of events as $n=10$ and probability of success is $p=0.5$. Hence, the probability of failure is $q$ given by

$q=1-p$

$q=1-0.5$

$q=0.5$

Since, the probability of success and failure is same and the number of times of occurrence of success is given by

$r=p$ × $n$

$r=0.5(10)$

$r=5$

Similarly, the number of times of occurrence of failure is the same. Hence, the probability of getting a success or failure is same that is $\frac{1}{2}$.

Final answer:

Hence, the probability of getting a 0 or success is 1 only.
