c. 3324
Step-by-step explanation:
We need to use the formula of Geometric CDF with π =0.02
P(x≤20) = 1 - (1-0.02)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - 0.6676
P(x≤20) = 0.3324
Therefore the probability that the first such ejection occurs within the first 20 Visa transactions is 0.3324
