1. A coin is tossed 800 times and the outcomes were noted as: Head: 415, Tail : 385. Find the probability of the coin showing up (i) a head, (ii) a tail.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

From the question it is given that,

A coin is tossed 800times, so total number of trials is 800.

Let us assume that, {{A}_{1}} and {{A}_{2}} be the events of the coin,

So, total number of times A1 occurs = 415and the total number of times A2 occurs = 385

Then,

P({{E}_{{{1}_{{}}}}}) =\frac{415}{800}

= \frac{83}{160}

P({{E}_{{{2}_{{}}}}}) = \frac{385}{800}

= \frac{77}{160}
