Probability Introduction

which one is not a random experiment?

• tossing a coin

• throwing a die

• pulling a card from a deck of cards

• throwing a stone from the roof of the building

Any particular Performance of a random experiment is called

• event

• trial

• Random experiment

• Probability

The list of all possible outcomes of an experiment is called

• Random experiments

• Exhaustive events

• possible events

• Random events

Two events are said to be mutually exclusive events if

• the events occur at the same time

• the events have same probability

• the events cannot occur at the same time

• the events are unlike

which one is not a mutually exclusive event

• tossing a coin

• winning and losing a game

• running and walking

• running and sweating

if the events have equal probability of occurring, then they are said to be

• trail

• mutual events

• equally likely

• dependent

which one is equally likely events?

• Occurence of head and tail when tossing a coin

• rolling two dice

• Occurence of head and tail when tossing two coins

• drawing a ball from a bag of different coloured balls

if the occurence of one event does not affect the occurence of other,

then they are called______events

• equally likely

• mutually exclusive

• Independent

• Exhaustive

which are not independent events?

• tossing a coin two times

• rolling a dice two time

• drawing a ball from a bag with replacement

• drawing a ball from a bag without replacement

• If A and B are dependent

• If A and B are mutually exclusive

• If A and B are not mutually exclusive

• If A and B are equally likely
