Answer 1

Answer:

Hey....!!!!

As we know probability of any event is 1...

So as given here P(E)=0.72

Then P(F)=1-0.72

P(F) =0.28

Hope this helps...❤❤☺☺

Answer 2

Solution:

Given:

=> P(E)=0.72

To Find:

=> P(F) = ?

As, we know that maximum probability for occurrence of any event is 1.

∴ P(E) + P(F) = 1

=> 0.72 + P(F) = 1

=> P(F) = 1 - 0.72

=> P(F) = 0.28

Extra Info:

• Probability is the chances of a given event's occurrence which is expressed as a number between 1 and 0.
• Probability P (E) of an event E is given by

$\huge{\boxed{\boxed{\sf{\implies P(E) = \dfrac{Number\;of\;favorable\;outcomes}{Total\;number\;of\;outcomes}}}}}$
