Explanation:

Answer 2

Answer: The probability that Jo is not late on Monday = 0.6

Explanation:

The probability of getting late is independent on each day.

Also, for an event E

Probability of not E = 1- P(E) , where P(E) = Probability of happing E

Given: The probability Jo is late on a Monday is 0.4.

Then, the probability that Jo is not late on Monday = 1-0.4= 0.6

Hence, the probability that Jo is not late on Monday = 0.6
