To do:

We have to tell whether the given events are certain to happen, impossible, can happen but not certain.

Solution:

(i) Event: You are older today than yesterday. We keep growing older with time.

So, it is certain to happen.

(ii) Event: A tossed coin will land heads up.

Probability: When a coin is tossed, there are two possibilities either a head {H} or a tail {T}.

So, it can happen but not certain.

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

Probability: When a dice is tossed, there are only six outcomes i.e., {1, 2, 3, 4, 5, 6}

So, it is an impossible event.

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

Probability: The traffic light could be red, green, or orange.

So, it can happen but not certain.

(v) Event: Tomorrow will be a cloudy day. Weather cannot exactly be predicted hence not certain.

So, it can happen but not certain.
