One day, Karen bought 22 random cans of soup from a grocery store. Suppose that 5% of cans sold at that particular grocery store

zimovet [89]

Answer:

0.6765 = 67.65%

Step-by-step explanation:

This situation can be treated as a binomial model with probability of success (dented can) of p = 0.05.

In 22 random trials, the probability of at least one success is determined by:

$P(X>1) = 1-P(X=0)\\P(X>1) = 1 - (1-p)^{22}\\P(X>1) = 1 - (1-0.05)^{22}\\P(X>1) =0.6765$

The probability that Karen has bought at least one dented can is 0.6765 or 67.65%.
