# There are 30 boys and 25 girls in a class. A student is chosen at random. Find the probability that the chosen student is a boy

Given that,

Number of boys = 30

Number of girls = 25

Therefore, the total number of students 30 + 25 = 55 = n(S)

Let X be the event of choosing a boy.

Hence, n(X) = 30

Therefore, the probability of choosing a boy, P(X) = n(X)/n(S)

P(X) = 30/55

P(X) = 6/11
