Question

The probability of happening of an event is 45%. The probability of an event is
a) 45
b) 4.5
c)0.45
d) 0.045​

Answer 1

Answer:

(c) 0.45

Given, probability of an event happening is 45%

45% is the same as 45/100

Thereby, probability of the event happening is 45/100

This is equal to 0.45

Therefore, probability of the event happening is 0.45

Answer 2

Solution:

Given:

⇒ Probability of happening of an event = 45%

To Find:

⇒ Probability of event

Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.

⇒ Probability of happening event = 45/100

⇒ Probability of happening event = 0.45

⇒ Probability of non happening event = 55/100

⇒ Probability of non happening event = 0.55

Hence, the correct option is (c) 0.45.

Extra Info:

• Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

• $\sf{Probability=\dfrac{Number\;of\;favorable\;outcomes}{Total\;number\;of\;outcomes}}$
