(Q) 26 cards each bearing one English letter are kept in a box. One card is drawn at
random. What is the probability that the card drawn is a vowel card?
Answers
Step-by-step explanation:
n(s)=26
let A be the event to get a vovel card
A=[A,E,I,O,U]
n(A)=5
p(A)=n(A)/n(S)
=5/26
so,
therefore 5/26 is the probability to get a vovel card in the deak
Given,
Number of cards kept in a box, bearing one English letter each = 26
To find,
The probability that the card drawn randomly is a vowel card.
Solution,
We can simply solve this mathematical problem using the following process:
Mathematically,
The probability of occurrence of a favorable event = P (favorable event)
= (Total number of occurrence of the favorable event) / (Total number of occurrence of all possible events)
= (Total number of occurrence of the favorable event) / (Total number of trials)
As per the given question;
The favorable event is the occurrence of a vowel, that is either A, E, I, O, or U, respectively.
So, the number of favorable events = 5 {A, E, I, O, U}
And, the total number of trials
= total number of cards
= total number of alphabets = 26
Now,
The probability that the card drawn randomly is a vowel card
= (Total number of occurrence of the favorable event) / (Total number of trials)
= (Total number favorable events) / (Total number of cards)
= Total number of vowels / total number of alphabets
= 5/26 = 0.19 approx
Hence, the probability that the card drawn randomly is a vowel card is equal to 5/26, which is approximately equals to 0.19.
