Chapter 3: Data Handling

Solution:-

It is certain to happen.

(ii) A tossed coin will land heads up.

Solution:-

It can happen but not certain.

(iii) A die, when tossed, shall land up with 8 on top.

Solution:-

It is impossible because there are only six faces on a die marked as 1, 2, 3, 4, 5, and 6 on it.

(iv) The next traffic light seen will be green.

Solution:-

It can happen but not certain.

(v) Tomorrow will be a cloudy day.

Solution:-

It can happen but not certain.

Solution:-

From the question, it is given that

There are 6 marbles in the box with numbers from 1 to 6 marked.

Probability of drawing a marble with number 2 = Number of favourable outcomes /

Number of possible outcomes

= (1/6)

(ii) What is the probability of drawing a marble with the number 5?

Solution:-

From the question, it is given that

There are 6 marbles in the box with numbers from 1 to 6 marked.

Probability of drawing a marble with number 5 = Number of favourable outcomes /

Number of possible outcomes

= (1/6)

Solution:-

A coin has two faces: one is the Head, and the other one is the Tail.

Now, one team can choose either Head or Tail.

The probability of our team starting first= Number of favourable outcomes /

Number of possible outcomes

= ½
