Answer 2

Problem:

Монету подбрасывают 7 раз. Какова вероятность, что выпадет "решка" хотя бы 1 раз?

Solution:

To find the probability of getting at least one "heads" in 7 coin tosses, we can use the complement rule. The complement rule states that the probability of an event not happening is equal to 1 minus the probability of the event happening.

To calculate the probability of not getting any "heads" in 7 tosses, we need to find
