Coin Toss A coin is tossed three times in a row, and the outcomes of each toss are observed.

(a)	Find the sample space for this experiment.
(b)	Find the probability of getting three heads.
(c)	Find the probability of getting two or more heads.
(d)	Find the probability of getting tails on the first toss.

(a)

To find:

The sample space for the experiment.

Approach:

The sample space of an event is given by,

S=(number of possible outcomes)number of repetitions

Calculation:

Total number of possible outcomes will be two as a coin can either have a head or a tail.

The sample space for the experiment is,

S=(2)

(b)

To find:

The probability of getting three heads.

(c)

To find:

The probability of getting two or more heads.

(d)

To find:

The probability of getting tails on the first toss.
