Question

Pieces of paper with each letter of the alphabet are placed into a jar. A student draws
4
pieces of paper at random, replacing the paper after each draw. Find the probability that a letter A through G is drawn at least once from the jar.
Round your answer to two decimal places.

Answer 1

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.
