Question

What can be the probability of an event from the following.? 0.4 1.004 11/23 18/11

Answer 1

Answer:

Option A Is Right

WHAT IS PROBABILITY?

• probability is the possible outcome of an event

• it predicts the possible outcome

EXAMPLES:

• outcome of a die rolled

• a card drawn randomly from deck of cards

• a ball picked randomly from a bag

• outcome of a tossed coin.

SOLUTION FOR QUESTION:

• the probability of an event must lie between 0 and 1

• it must neither be 0 nor 1

• the value must be rational.it can not be irrational

NOTE:

• Rational number has finite value

• irrational number has infinite value.

VERIFICATION

• OPTION A: 0.4

it is finite and lies between 0 and 1

• OPTION B:1.004

it is greater than one

• OPTION C :11/23

11/23=0.478...........

it is infinite

• OPTION D:18/11

18/11=1.63.......

it is infinite as well as greater than 1

ANSWER:

option a 0.4 satisfies all condition.

so the probability of an event may be 0.4
