Question

A letter is chosen at random from the word PROBABILITY.find the probability that it is a vowel.?

Answer 1

Answer:4/11 is the probability

Step-by-step explanation:

S={p,r,o,b,a,b,i,l,i,t,y}

n(S)=11

A={o,a,i,i}

n(A)=4

P(A)=n(A)/n(S)

=4/11

Hope it helps

Answer 2

Answer

The total number of outcome 11

The total probable outcome of vowel is A,I,I,O.

The number of total probable outcome of vowel is 4.

Therefore P(e)=4/11
