Answer:
0.3277 = 32.77%
Step-by-step explanation:
If we want the probability for Sasha being late after the fifth day, we need that in the first five days she is not late, which has a probability of 1 - 0.2 = 0.8
So, multiplying the probability for each day, we have that:
P = 0.8 * 0.8 * 0.8 * 0.8 * 0.8 = 0.3277 = 32.77%
So we have a probability of 32.77% that Sasha's first delay will occur after the fifth day.
