The number of trials and the probability of obtaining success will be given as P(X ≤ 2) = 0.9728.
<h3>How to find that a given condition can be modeled by binomial distribution?</h3>
Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
X \sim B(n,p)
The probability that out of n trials, there'd be x successes is given by
![\rm P(X =x) = \: ^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=%5Crm%20P%28X%20%3Dx%29%20%3D%20%5C%3A%20%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
Assume the random variable X has a binomial distribution with the given probability of obtaining success.
Then the number of trials and the probability of obtaining success will be
P(X ≤ 2), n = 4, p = 0.2
Then we get
![\rm P(X =2) = \: ^4C_2(0.2)^2(1-0.2)^{4-2}\\\\P (X=2) = 6 \times 0.0256 \\\\P (X=2) = 0.1536](https://tex.z-dn.net/?f=%5Crm%20P%28X%20%3D2%29%20%3D%20%5C%3A%20%5E4C_2%280.2%29%5E2%281-0.2%29%5E%7B4-2%7D%5C%5C%5C%5CP%20%28X%3D2%29%20%3D%20%206%20%5Ctimes%200.0256%20%5C%5C%5C%5CP%20%28X%3D2%29%20%3D%200.1536)
Then the cumulative probability will be
![\rm P(X\leq 2) = 0.9728](https://tex.z-dn.net/?f=%5Crm%20P%28X%5Cleq%202%29%20%3D%200.9728)
