Find the probability of 2 or 3 successes in 7 trials of a binomial experiment in which the probability of success in any one trial is 42%. round to the nearest tenth of a percent.

53.7 %

Step-by-step explanation:

Given:

Number of trials,

Number of successes,

Probability of success,

Therefore, probability of failure,

The Bernoulli's distribution for successes out of trials is given as:

So, probability of 2 or 3 successes is given as:

Therefore, the probability of 2 or 3 successes in 7 trials of a binomial experiment is 53.7 %.
