Question

Give examples of 5 experiments that have equally likely outcomes and five more examples that do not have equally likely outcomes.

Answer 1

Dear Student,

Equally likely outcome= The outcomes having equal probability to occur are known as equally likely outcome.

Examples:

1) Tossing a coin: Since coin has two possible outcome ,head and tail
The probability to occur head = 1/2 ,and same as the probability to occur tail = 1/2

thus Tossing a coin is an equally likely event.

2) Rolling a dice= since dice has six faces numbered 1,2,3,4,5 and 6

probability of occurring 1 = probability of occurring 2 =probability of occurring 3 = probability of occurring 4 = probability of occurring 5 probability of occurring 6 = 1/6

Since all outcomes have equal probability to occurs,so rolling a dice s equally likely event.

3) state true and false:

True and false question and answers have two equally likely outcomes, I.e. True or False
probability to occur true = probability to occur false = 1/2

hence it is equally likely event.

4) playing a card: playing a card is an equally likely event because, a deck has 52 cards and probability to swipe one card of any color is 1/52.

5) Drawing balls from a bag: if a bag have equal number of colourful balls,then drawing one ball is equally likely outcome.

Don't have equally likely outcome:

Rest all the events don't have equally likely outcome.

for example:
1) tossing of two coin simultaneously

2) rolling two dice,

3) drawing a ball from a bag having different size and different colours.

4) Rolling a Matchbox; since Matchbox don't have all the sides equal

Hope it helps you.

Answer 2

Hi ,

Five examples of equally likely outcomes.

1 ) Winning chance of toss of two

teams .

2 ) Getting even or odd from natural

number set .

3 ) If a bag have 1 red and 1 blue ball

getting a red ball from it .

4 ) Selecting of a correct answer to a

True/False type of questions.

5 ) Tossing a coin and getting head or

tail.

Examples of not have equally likely

outcomes :

1 ) A driver attempts to start a car .

The car starts or doesn't start .

2 ) Getting a number less than 10 from

real numbers.

3 ) Getting a number greater than 90

from rational number set .

4 ) The last digit is odd number in the

first 10 multiples of 5.

5 )A trial is made to shoot a basket ball.

She/he shoots or misses the shot .

I hope this helps you.
