Answer 1

ГИГАБАЙТ
2 буквы Г из 8 букв
2 буквы А из 8 букв

Итого благоприятных исходов: 2 + 2 = 4
Вероятность: 4 / 8 = 0.5

Answer 2

To calculate the probability of randomly selecting the letters "Г" or "А" from the word "ГИГАБАЙТ," we first need to determine the total number of letters in the word and then count the occurrences of the letters "Г" and "А."

1. Total number of letters in the word "ГИГАБАЙТ": 7
2. Occurrences of the letter "Г": 2
3. Occurrences of the letter "А": 1

Now, we can calculate the probability:

Probability (selecting "Г" or "А") = (Number of "Г" + Number of "А") / Total number of letters Probability (selecting "Г" or "А") = (2 + 1) / 7 Probability (selecting "Г" or "А") = 3 / 7

So, the probability of randomly selecting the letter "Г" or "А" from the word "ГИГАБАЙТ" is 3/7 or approximately 0.4286 (rounded to four decimal places).
