Explanation Given: The probability that a birth will result in twins is 0.027 . Out of 100 births in a hospital, there will be at most 2 sets of twins. Assuming independence (perhaps not a valid assumption). Formula used: Binomial probability rule If p is the probability of success in a single trial of a binomial experiment, the probability of x successes and n − x failures in n independent repeated trials of the experiment are P = C n x p x ( 1 − p ) n − x And The number of combinations, or subsets, of n distinct things taken r at a time, where , r ≤ n can be calculated as follows. n C r = ( n P r ) r ! = n ! r ! ( n − r ) ! Calculation: Take 100 births in a hospital as independent trials and a success occurs if a twin is born. Since, Out of 100 births in a hospital, there will be at most 2 sets of twins. So, P ( at most 2 ) = P ( x = 0 ) + P ( x = 1 ) + P ( x = 2 ) So, this is a binomial expression with: p = 0.027 , n = 100 and x = 0 , 1 , 2 . Then, by the binomial probability rule: P = C n x p x ( 1 − p ) n − x Put the values, At x = 0 , P ( x = 0 ) = C 100 0 ( 0.027 ) 0 ( 1 − 0.027 ) 100 − 0 = 100 ! 0 ! ( 100 − 0 ) ! ( 0

Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…
