I.Explain the outcome of the following experiment.
PROBABILITY
If these are the letters found inside the box and you are to get or pick a letter from the box,
1. What is the chance of picking a letter B from the box?Why?
2. What is the chance of picking a vowel letter?Why?
3. What is the chance of getting a consonant letter? Why?
4. What is the chance of picking an A ?Why?
Answers
Answer:
Okay, so this is a question of Probability,
The first and foremost rule of solving these sums, is to keep in mind- i) No. of Possibilities ii) No. of possible event to occur iii) Possibility of something to not occur
Total no. of letters in English = 26 [General GK]
1.
No. of Events(or no. of B)= 1 (it is because B can occur only once in entire set of English alphabet, hence u can possible pick B only once)
Probablity of picking a B= [no. of event] ÷ [total no. of events]
=1/26
Hence picking a B from the set has a probability of 1/26...(Ans.)
2.
No. of events(or no. of vowels)= 5 (a, e ,i ,o ,u are the vowels and 'y' is yet not officially included)
Clearly, the Probabilty= 5/26
Hence, picking any vowel from the set has a probability of 5/26...(Ans.)
3.
Excluding the 5 vowels,
number of consonants= 21
Clearly, the Probabilty= 21/26
Hence, picking any vowel from the set has a probability of 21/26...(Ans.)
4.
No. of Events(or no. of A in english alphabet)= 1
Probablity of picking an A=1/26
Hence picking an A from the set has a probability of 1/26...(Ans.)
