Answer:
0.71 to 2 decimal places.
Step-by-step explanation:
The Probability that a letter A through G is drawn in 1 draw = 7/26.
The probability that a different draw other A-G is made = 1 - 7/26 = 19/26.
Probability ( No A-G drawn in 4 draws) = (19/26)^4 = 0.2852.
Therefore, the probability that A-G is drawn at least once = 1 - 0.2852.
= 0.71 to 2 decimal places.
