Question

A letter is chosen at random from english alphabet find the probability that the latter chosen precedes g

Answer 1

Step-by-step explanation:

Given :-

A letter is chosen at random from english alphabet .

To find :-

Find the probability that the letter chosen precedes g?

Solution :-

Total number of letters in the English alphabet = 26

(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z)

Total number of all possible outcomes = 26

Let a letter chosen at random from English alphabet be an event E.

The letters precedes g = a,b,c,d,e,f,

Total letters = 6

Number if favourable outcomes = 6

We know that

Probability of an event E is P(E)

= Number of favourable outcomes/Total number of all possible outcomes

Probability of getting a letters which precedes g

= P(g)

=> 6/26

=> 3/13

P(g) = 3/13

Answer:-

The probability of getting a letter which precedes g = 3/13

Used formulae:-

→Probability of an event E is P(E)

= Number of favourable outcomes/Total number of all possible outcomes
