The probability that at least one of them has an injection-site reaction is: 0.5356.

Probability

Using this formula

Probability of atleast one= 1- (1- Proportion)^n

Where:

Proportion=.12

Sample size=n=6

Let plug in the formula

Probability of atleast one=1-(1-.12)^6

Probability of atleast one=1-(.88)^6

Probability of atleast one=1-.4644041

Probability of atleast one=0.53559

Probability of atleast one=0.5356 (Approximately)

Therefore the probability that at least one of them has an injection-site reaction is: 0.5356.
