The probability of a bus being late on any day is 0.2 James gets the bus on Monday and on Tuesday. What is the probability that both buses are on time?
Answers
The probability that both buses are on time = 0.64
Step-by-step explanation:
Given:
Probability of a bus being late on any day is 0.2
To find out:
The probability that the bus is on time on both Monday and Tuesday
Solution:
Given that probability of bus being late is 0.2
Therefore, probability of bus being on time = 1 - 0.2 = 0.8
The bus being on time on any day of the week is an independent event
Therefore,
Probability that the bus is on time on Monday and on Tuesday
= Probability that the bus is on time on Monday × Probability that the bus is on time on Tuesday
= 0.8 × 0.8
= 0.64
