Question

Which of the following are examples of mutually exclusive events? Group of answer choices

walking and running at the same time
all of these
rain and a cloudless sky
snow and a temperature of 10° Celsius

Answer 1

Option B. All of these.

Step-by-step explanation:

Mutually exclusive events are events that can occur simultaneously. If two events are mutually exclusive, it means that they can occur at the same time. For example, the two possible outcomes of a coin flip are mutually exclusive; when you flip a coin, it cannot land both heads and tails simultaneously.

* Walking and running at the same time are mutually exclusive because it is possible to walk and also run at the same time at a certain pace (also means speedy walking).

* Rain and a cloudless sky are mutually exclusive (possible) if the concentration of liquid water in the air isn't too high.

* Snow and a temperature of 10° Celsius are mutually exclusive because if the depth of cold air aloft is great enough, then the snowflake will survive the trip downwards even at 10° Celsius.

Therefore, all the options provided to the question are correct since they are all mutually exclusive.

Answer 2

The correct is answer is All of these because:

• walking and running at the same time

• rain and a cloudless sky

• snow and a temperature of 10° Celsius

are all mutually exclusive events.

Step-by-step explanation:

walking and running at the same time :

Humans can multi task and engage the brain in coordinating psycho motor, affective and cognitive processes all at once but in the case of activities such as running and walking, it is impossible because, the same organs, neurons and muscles are needed for both activity.

Rain and a cloudless sky :

Rain occurs after a process of condensation. When the vapor that rises, cools off and form a cloud. Rain happens when the cloud formed dissolves. In other words, rain is clouds in liquid state and there is definitely no rain without a cloud.

Snow and a temperature of 10° Celsius:

Snow is synonymous with extreme cold temperatures usually below 0° Celsius. When it snows, temperature levels ranges from zero degrees to -10° Celsius. Therefore, a temperature of 10° Celsius can never occur when it is snowing.
