How do you show less than or equal too on a number line?
NISA [10]
It is like if you have two number lines. Then one has a pointer at 0, and the other one has the pointer facing at 2 then it will be lesser because the first one has 0 or if it turned around it would be greater. If it is equal then it would have the same number, but watch out if it is a negative number.

suppose a weather app says that the probability of rain today is 30%. What is the complement of the event ""rain today"" what is
ValentinkaMS [17]

Answer:

The complement event would be: "No rain today"

Its probability would be 70%

Step-by-step explanation:

Given the event:

A= rain today

The probability of rain today is 30%

P(A)=30%=0.3

The complement event has all the values that are not included in the event.

The complement event would be:

A'= No rain today

The probability of a event is the subtraction between 1 and the complement event:

P(A')=1-P(A)

Then, the probability of the event "No rain today" will be:

P(A')=1-0.3=0.7=70%
