In a class competition there are 4 prizes to be distributed, 2 each to boys and girls. If each boy or girl is eligible for only one prize, find the number of ways in which these prizes can be distributed if there are 20 boys and 15 girls. => 35 C 4 or 35 P 4 or 75 or 1..

A mother wants to distribute candies to her two sons according to the ratio of their ages. The younger son is 5 and the older one is 8. If the younger son receives 10 candies, then how many candies will the older son receive? => 15 or 17 or 14 or 16..

The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of mark..

Frequency Distribution - A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an arra..

A trial, which has only two outcomes i.e., "a success" or "a failure", is called a Bernoulli trial . The probability distribution of the number of successes, so obtained is called the binomial distribution..

Geological Distribution - The organisms show particular patterns of distribution on earth. The distribution of the species give an indication of how the earth was earlier. It is believed that the earth was a single mass called the Pangea. It consisted of two ..

Binomial Distribution - A trial, which has only two outcomes i.e., "a success" or "a failure", is called a Bernoulli trial. Let X be the number of successes in a Bernoulli trial, then X can take 0 or 1 and P(X =1) = p = "probability of a success" P(X = 0) = 1 - p = q = "probabil..

A trial, which has only two outcomes i.e., "a success" or "a failure", is called a Bernoulli trial. Let X be the number of successes in a Bernoulli trial, then X can take 0 or 1 and P(X =1) = p = "probability of a success" P(X = 0) = 1 - p = q = "probability of failure". Consider a random..
