Question

Theory-Probability is such a native part of your life that you rarely think about it. Though,

every time you use a word like “might,” “may,” “undoubtedly,” “without fail,” or “may be,

“you invariably use or experience probability. Scientists and great mathematicians like to

express probability more accurately for example, if you toss a coin in the air, the

probability (P) that it will land heads or tails.

Materials required- A4 papers, pencil, four coins of same denomination

Procedure- Using a paper and pencil, draw circles with an “H” or a “T” in the centre of the

paper to illustrate the different results when you toss these four coins. Now perform the

following steps and answer the questions

Step 1

Using the circles drawn as mentioned above, express the following

• The probability of getting three heads while tossing the coins.

• The probability of getting three tails while tossing the coins.

• The probability of getting one head and three tails while tossing the coins.

• The probability of getting one tail and three heads while tossing the coins

Step 2

Try tossing these four coins 5 times and write down the outcomes. Are the probabilities of

the events in step 1 same or they change when the coins are tossed 5 times? Justify your

answer..​
