PROBABILITY

The chance of an event happening when expressed quantitatively is probability.

• CLASSICAL APPROACH

• EMPIRICAL APPROACH

• NONE

If we toss a coin, getting a head or a tail are

• EQUALLY LIKELY

• NOT EQUALLY LIKELY

• MUTUALLY EXCLUSIVE

If two events cannot occur simultaneously (at the same time), in a single trial they are said to be

• EQUALLY LIKELY

• NOT EQUALLY LIKELY

• MUTUALLY EXCLUSIVE

A number between 0 and 1 that is used to measure uncertainty is called

• Random variable

• Trial

• Simple event

• Probability

The probability based on the concept of relative frequency theory is called

• Empirical probability

• Classical probability

• Both (1) and (2)

• Neither (1) nor (2)

If A is any event in S and its complement is A’ then, P(A′) is equal to

• 1

• 0

• 1−A

• 1−P(A)

Which of the following cannot be taken as probability of an event?

• -1

• 1

• 0

• 0.5

A particular result of an experiment is called

• Outcome

• Simple event

• Trial

• Compound event

The six faces of the dice are called equally likely if the dice is

• Small

• Fair

• Round

• Six-faced

A collection of one or more outcomes of an experiment is called

• Event

• Outcome

• Sample point

• None
