(a) Explanation Given: Births of boys and girls are equally likely. Total number of births = 19 Explanation: As births of boys and girls are equally likely,, the probability of getting a boy is 1 2 . and the probability of getting a girl is 1 2 . Probability that all the 19 births give boy: P ( all boys ) = C ( 19 , 19 ) × ( 1 2 (b) To determine The probability, in any one of the hospitals, of having a string of all boys. (c) To determine The probability that at least 1 of 5700 hospitals would have a string of all boys. (d) To determine The reason of the actual probability of a hospital having a string of 19 boy births is higher than the value calculated in part(c).

Compound Probability

Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Tree diagram

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axi…

Conditional Probability

By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between…
