Two coins are tossed simultaneously 100 times. We obtained :
Two Heads: 23 times; One Head : 56 times; Zero Head: 21 times. When two coins are tossed at random, what is the probability of getting : Zero Head?

Five cards numbered 1 to 5 are placed in a bag. A card is drawn from the bag 30 times. Each time, the number on the drawn card is noted and the card drawn is replaced. The outcomes are tabulated as shown below :

Outcome	1	2	3	4	5
Frequency	4	10	7	5	4

If a card is now drawn at random, find the probability that the card drawn bears the number :
(i) 2
(ii) 3
(iii) 5

A die is rolled 150 times and the outcomes are noted which are tabulated as shown below :

When a die is rolled at random, find the probability of getting a :
(i) 1
(ii) 4
(iii) 5
