The probability of event A occurring is 50%, and the probability of event B occurring is 25%. Events A and B are nonsimultaneous
Misha Larkins [42]

Answer:

The probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur = 0.375

Step-by-step explanation:

The probability of event A occurring = 50% = 0.5

The probability of event B occurring = 25%  = 0.25

Events A and B are non simultaneous events.

The probability of event B does not occur = 1 - P(B)

= 1- 0.25

= 0.75

So the probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur

= 0.5*0.75

= 0.375

Thank you.

vampirchik [111]

Answer:

D) 1000

Step-by-step explanation:

<u><em>The options of the question are</em></u>

A) -1000 B) -7 C) 7 D) 1000

we know that

The sea level is the reference value to represent elevation, and it is considered as zero level.

Above sea level is considered positive and below the sea level is considered negative

we have

New Orleans is 7 feet below sea level

so

New Orleans elevation is -7 ft

Oklahoma is 1000 feet above the sea level

so

Oklahoma elevation is +1000 ft

therefore

Oklahoma City's elevation is represented by 1000
