Harpreet tosses two different coins simultaneously. What is the probability that she gets:
(i) at least one head ?
(ii) one head and one tail ?
=Number of outcomes favourable to E (m)Number of all possible outcomes of the experiment (n).
Which of the following options correctly explains the relationship between m and n?
- m≥0 , n>0, m≤n
A test paper contains 100 true/false questions. The number of questions with answer "true" was 59. Find the probability that a question’s answer is "false".
Theoretical probability of an event A is given as AB where
S1 : A is the number of outcomes favourable to E
S2 : B is the total number of possible outcomes.
S1 and S2 are false
S1 and S2 are true
S1 is true and S2 is false
S1 is false and S2 is true
A carton consists of 100 shirts of which 88 are good, 8 have minor defects and 4 have major defects. Jimmy, a trader accepts shirts only which are good. But, Sujatha, another trader will reject shirts which have only major defects. One shirt is drawn randomly. Find the probability that the shirt selected is (i) Acceptable to Jimmy (ii) Acceptable to Sujatha
The theoretical probability of getting a head in a toss of a coin is
In theoretical probability approach, the outcomes are
A student was tested on 100 true or false questions. The number of questions whose answers were true was 59. Find the probability that a question’s answer is false.
According to the theoretical probability approach of tossing a coin, the probability of getting a head is (in decimal form)
Empirical probability is defined as
Probability based on guess
Probability based on theory
Probability based on instincts
Probability based on experimental data
