If a person picks a pair of different Months, what is the probability that both months (different) have less than 31 days?

15.15% probability that both months (different) have less than 31 days.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Also, the order of the months is not important. For example, picking July and August is the same as picking August and July. So the combinations formula is used to solve this problem

Combinations formula:

is the number of different combinations of x objects from a set of n elements, given by the following formula.

There are 12 months, of which February, April, June, September and November, that is, 5 of them, have less than 31 months.

Desired outcomes:

Picking 2 months from a set of 5(those with less than 31 days). So

Total outcomes:

Picking 2 months from a set of 12(all the months). So

Probability:

15.15% probability that both months (different) have less than 31 days.

step-by-step explanation:

8+13=21

21+8=29

29+6=35

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
