Question

What is probability that the consonats is unchanged in letterr math?

Answer 1

here in letter math
S = { m , a , t , h }
n(S)= 4

let event A= unchanged in letter math
A={ m , a , t , h }
n(A)= 4

P(A) =n(A)/n(S)
P(A) =4/4
P(A) = 1

therefore the probability that constant is unchanged in letter math is 1 .
