the likelihood that

a) Between eight and ten orders were reserved through site?

In Canada, the postal codes are three numbers and three letters. The characters of the postal codes consistently substitute, beginning with a letter: letter number letter number letter number.

a) what number conceivable postal codes are there in Canada? (Keep in mind: there are 26 letters in the Canadian letter set.)

b) What is the likelihood that a Canadian postal code doesn't have any rehashed letters or numbers? (e.g, the above postal code has the number 2 rehashed)

c) What is the likelihood that a Canadian postal code does have at least one rehashed letters or numbers?

air contamination control experts in southern california screen the measure of ozone, carbon dioxide, and nitrogen dioxide noticeable all around on an hourly premise. the hourly time arrangement information

display irregularity, with the degrees of poisons showing designs over the course of the hours in the

day. on july 15, 16, and 17, the accompanying degrees of nitrogen dioxide were seen in the

downtown territory for the 12 hours from 6:00 a.m. to 6:00 p.m.

On the off chance that emotional probabilities are controlled by the

technique recommended in Exercise 16, the third propose of

likelihood may not be fulfilled. Be that as it may, advocates

of the abstract likelihood idea as a rule force this

propose as a consistency model; at the end of the day, they

respect abstract probabilities that don't fulfill the pos-

tulate as conflicting.
