प्रश्न

A coin is tossed 3 times and the outcomes are recorded. How many possible outcomes are there?

संक्षेप में उत्तर

उत्तर

When a coin is tossed once, the number of outcomes is 2 (Head and tail), i.e., in each throw, the number of ways of showing a different face is 2.

Thus, by multiplication principle, the required number of possible outcomes is 2 × 2 × 2 = 8
