An experiment suc

Answer :

It is given in the question that,

Probability of failure = x

And, probability of success = 2x

x + 2x = 1

3x = 1

Let us now assume

Also, X be the random variable that represents the number of trials

Hence, by binomial distribution we have:

Probability of having at least 4 successes

= P (X = 4) + P (X = 5) + P (X = 6)
