Answer:

a. .02 * .02 = .0004  

b. (1 - .02 - .19) = .79; .79*.79 = .6241

Step-by-step explanation:

The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.

What is Probability?

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Probability that the bus will be late is 0.19

Probability that the bus will be early is 0.02.

The probability that the bus will arrive early next two days is

= 0.02 * 0.02

=0.0004

The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.

The probability that the bus will arrive on time next two days

= (1 - 0.02 -0.19) = 0.79

The probability that the bus will come on time is more as the probability of coming early or late is less.
